I had this idea for a while and since i was wanting to draw something i though "Eh, why not?" :3
And of course there must be rules xD
You can:
Add/remove things
Edit the lines
Add shading/highlighting
Add a background
Use in competitions
Move my signature
You cannot:
Take off CS
Remove my signature
Use for profit
Claim lines as your own
Don't forget to click lock alpha for the respective add on color layers so you wont color outside the lines (unless you want to, of course xD).
ETA
Added a sweat drop and two 'sigh puffs' :3
