We're now ready for people to start working on the artwork! Here are the guidelines that every picture must conform to:
180x196
Black on white (no grayscale)
Drawable with a 4x4 pen
You can use any drawing program you want (Photoshop, GIMP, MS Paint, etc), but make sure your resulting image is in a lossless format like PNG.
I've made a utility to check if an image can actually be drawn in Brain Age
http://pjgat09.github.io/BrainAgeTools/
When you finish an image in your image editing software check it with this tool. This tool will crop your image to 180x196 and will remove any pixels that are not black. It will then check that the image can be drawn with a 4x4 pen. Any pixels that can not be recreated with a 4x4 pen will be highlighted red. You will need to fix those sections.
Pick an image from the script that hasn't been claimed/finished yet, and let me know you're working on it via PM. I don't have a fancy submission method ready yet, so when you've finished an image PM me with a link to it on imgur or similar. Feel free to PM me with any questions.
