Sci-fi Character in progress please leave me some feedback!

Hi this is my Character I have been working on, give me your thoughts!
I am also new to mudbox, is this good for the first time using mudbox?

i think maybe yes good but textur not so god but yes how polys many?

It's a very nice start. I like the proportions.
The only critique is the way you present it for review.
It's dark on a dark background so it's difficult to see details.
Add more lights or show it on a bright background.
