I stumbled upon this sorry if its already been mentioned :3 I tried it with the doodles :3

http://krita.org/featuresKrita is a KDE program for sketching and painting, offering an end-to-end solution for creating digital painting files from scratch by masters, is available for Linux and Windows and here you can find all the features that Krita has for you.
Interface and workspace:
Krita has a user-friendly interface. In Settings you can choose the color theme, which toolbars and dockers you want to use and edit the keyboard shortcuts. You can save a given set of dockers as a workspace and switch between them.
File Formats Supported:
Saves to:
.kra, OpenRaster document, PSD image, PPM, PGM, PBM, PNG, JPEG-2000, JPEG, BMP Windows, XBM, TIFF, EXR, PDF.
Import:
.kra, EXR, OpenRaster document, PSD image, Gimp image, PPM, PGM, PBM, PNG, JPEG-2000, PDF, ODG draw, BMP Windows, XPM, GIF, XBM, Krita Flipbook, Adobe DNG negative and Camera RAW.
Painting:
Krita has pixel, smudge, duplicate, filter, hairy, hatching, texture, chalk, color smudge, curve, deform, dyna, experiment (Alchemy), grid, particle, sketch and spray brushes.
Brush settings can be saved as presets and shared. Also, there is a full set of blending modes available when painting
and support for creating seamless textures to Krita (Image offset tool).
Canvas:
The canvas can be easily rotated and mirrored. The OpenGL canvas supports high-bit depth monitors. There is a large set of options available to create a no-distractions canvas-only painting mode.
Tools:
Krita has raster graphics and vector tools.
Vector tools: path, selection, text, artistic text, calligraphy, fill and gradient.
Raster tools: freehand, line, rectangle, ellipse, polygon, polyline, star, path, dynamic movement, multihand, crop, move, transform and warp, measure, fill, gradient, color picker, assistants, perspective grid, grid, select rectangle, select ellipse, freehand selection, select polygon, select outline, fill select, select similar colors, path select, zoom and pan.
Dockers:
Dockers or palettes are basic gui building blocks. Krita has the following dockers availables: preset selector, layer management, channel management, various color selectors, tool options, shape selector, composition docker, undo history, pattern selector, task sets, scripts and various dockers for working with vector objects.
Filters:
Filters can be used directly on a layer, or as filter masks or layers. The effect of a filter is previewed on the image itself. New filters can be written in the OpenShiva language.
Krita has the following filters: levels, color adjustment curves, brightness/contrast curve, desaturate, invert, auto contrast, HSV adjustment, pixelize, raindrops, oil paint, gaussian blur, motion blur, blur, lens blur, color to alpha, color transfer, minimize channel, maximize channel, top/left/bottom/right edge detection, sobel, sharpen, mean removal, unsharp mask, gaussian noise removal, wavelet noise reducer, emboss horizontal only/in all directions/(laplacian)/vertical only/with variable depth/horizontal and vertical, small tiles, round corners, phong bumpmap, rotative blur, zigzag, mosaic, ray, wave expansion, seamlesser, planes, central absorption, mirror impose, random noise, anti bullify, tunel2, caleidoscope, slices, sphere, stereographic projection, contraction, sectorize, sea, lens correction, roundify, hipno, tunnel, bullify, random pick, droste, ripples.
Layers:
Krita has raster layers, vector layers, filter layers, programmatically generated layers, group layers and file-backed layers. Layers can have transparency, filter and local selection masks. Layers can be dragged and dropped within Krita, between instances of Krita or as images to and from other applications.
Vector layers support text, vector shapes and filters on vector shapes.
The layers can be rotated, scaled, converted, sheared, and you can mirror all layers in an image.
Generators:
Generators create pixels and can be used in generator layers. Krita has the following generators: checkerboard, concentric circles, disco, fractal explorer, metaball, moire, perlin noise, plasma, radial gradient, singleball, sun ray and supernova.
Generators are written in the OpenShiva language, which makes easier extending the set of available generators.
Color management, Color models and Channel depths:
Krita supports the following color models for creating and editing images:
RGBA, Gray, CMYKA, Law, YCbCr, XYZ in 8 bits integer, 16 bits integer, 16 bits floating point, 32 bits floating point.
Krita always uses color management. On Linux, if the monitor is correctly setup with colord or oyranos (gui settings applications available for GNOME and KDE), the display calibration will be used automatically.
