I made a little booklet just to draw art of Moonstorm in. I'm going to do this for a few more of my 'sonas and OCs. :)
This one is using Hobby Lobby's generic brand of what is somewhat like Poscas--on Yupo paper. It doesn't look as good as Poscas on Yupo (as you can tell on the next upload).
Transformers belongs to Hasbro/TakaraTomy, OC belongs to me.
