Yep Hundred eyes dragon is a beauty. It is great for Infernity which i run. I must admit Infernity is the best anime archtype ever they can rapidly swarm fields and summon army's of powerful Synchro's.
This is beautiful. I always found the card artwork for Hundred-Eyes to be rather... derpy. I'm surprised someone could actually make H.E. look good, but I'm not surprised it was you. :3
Also surprised by the style you took with it. I'd expect someone doing art of H.E. to keep to hard edges and dark, dark colors. The fact that this is pastelly, bright, and soft is actually a very interesting choice, which in my opinion turned out very well.
