Halo 3 custom helmet

[Radioactive Blueberry]

So, I'll try to give some C+C

first of all, I think the shading looks odd, might be the choice of color.
secondly, I don't think this actually looks like the halo 3 helm, try using a reference like:

try giving the sprite some detail so you can see what it is more clearly, and make the edges more "rounded", cuz imo it's a wee bit blocky

Edit: and yeah, what Zee said... And I now realize that it was very meaningless for me to post "what Zee said" because it is right above this post, making this comment very useless... so I'll be going now... yeah...
