If you want to color it in using the layers, set them to "lock alpha" and it will only color the darkened area.
And then the rules:
1. Don't erase my signature please
2. Feel free to use it for contests or references, but don't erase the signature.
3. You may edit the lines.
4. Since I am using it for my own art shop, the one thing you can't do is use it for yours. Sorry...
