I tried drawing in Autodesk Sketchbook.

Both the program and this picture suck.
Badly...

I could ramble on and on about how terrible this drawing program is but... You can just ask me what sucks about it and I'll try and give you all of the things it lacks/does terribly.

And if you use this program and are interested in a replacement... Well... I have a short list of replacement options for better programs, all in which are freeware.
