You used tethering a lot where it should be appearing to shine. Also the black looks flat due to lack of shading. You need a broader color selection. Also you shouldn't even use tethering on shine, but seeing as you did you used a lot. It just look flat and bland to me. Meh

I'm assuming it's supposed to be a helmet? The visor shouldn't go all the way across. Looks cheesy

Also it looks like the lower right of your visor is shaded into the helmet itself?
