Love the last one.
Btw, idk if you have a DS, but the Colors! homebrew for it is a great way to throw out these little sketches every chance you get. You should probably look into it
Actually, I was looking into that for a while but decided to hold of on it for now. Thanks for the advice!
You can get a card for around $20 if you already have a DS. I got the $40 one though, and have loved it every second I've had it. Just found it when I cleaned my desk too (I had lost it, and it had apparently gotten behind one of my monitors D:)
