Thanks! No portfolio yet, the only other place I published my art is in my Tumblr which it only has the stuff I finished and I was confident enough to post them and most of them I think you've already seen! HAHA.
Are you interested in pixel sprite art?
I'm slowly working various game mock-ups, my sprite art is still weak but I'll post them up once I feel confident enough to share it. You should make a weekly theme about game sprites!
