Okay, here it is, the last in the series of requested drawings for someone who wishes to remain anonymous: Amy Rose the Hedgehog, Cream the Rabbit, and Blaze the Cat from [i]Sonic the Hedgehog[/i] scuba diving.
I used regular, "window", and gel markers to create the background, but somehow the"window" and gel markers didn't come out as opaque as I thought. I guess either I have to get more markers or take more time drawing underwater backgrounds.
Anyway, I hope you like it.
