I really like the proportion and physic of this guy.. very nice. Nice going with the detailing aswell. Tho i think there are some errors perspectively. And the colours could be more... um...focused? To differrent here and there. But all and all.. Great!!
I think I like your Zeon rendition the best though, something about it looks like it could fit right into the Titans Test Type series of mecha.
Great stuff!
