What do you think of my robot?

Moikle

This is my first thread here, so hi.

I am looking for critique on this robot/mech character I have been working on for a couple of afternoons. Probably going to make some renders and use it in my portfolio when applying for university.












I know I need to work on adding a bit of finer detail to him before I go into texturing. Any techniques you can share for that?
