My Robot model

good evening guyz
so whats up ? im having my ever longest leave of 7 days...  any way i couldn't make anything only playing games.got a nice game called Snipe elite V2. a good game i got after a long time.
by the way this is a Robot model i made for some request of my work place. actually not a very good model..making some comments is up to you.
rendered in Mental Ray just as same

I made and rendered this in my HP Dv6 laptop... it was  difficult to handle a more detailed model in my lap.. that's why i couldn't make the environment
