My general observations:
The Dreads are by far my favorite! they look awesome, they have an awesome texture! Good work!
I also like the texture of the Xenomorph skin. It reminds me of whale skin. Much how I imagine a xenomorph's skin should be.
the armor coloring is great, but I think it may be a little to similar to skin tone.
Overall good work. I dream of owing an awesome paint of this sculpt. This is by far Narin's best IMO!
