Lessee, what do we have here ?...
A demonic creature - not bad, a fighter study - got style, but there is work to do, a Madox in hover mode - ha ha, didn't even remember about that one until I found back that sheet, and a mecha head I especially like - that seems to have been inspired by Takashi Akaishizawa's Fairyza robots ( http://rakugakids.free.fr/Fairyza.jpg ), though it is closer to a mix of the Dangaioh, GP02 and S-Gundam, my eternal references when it comes to create a mecha facial mask that looks like a samurai's to inspire fear...
