The base fits really well with those mud u had on the tank before.
Two things i gotta object though. one being ... there is grass in the bloody battlefield of 40K??!!! lol, just kidding.
The other however, is that I really don't think a Space Marine needs binocular, with their eyes being like 100times better than regular humans' and the one you got has a bionic eye implant!! =P
but it's alrite, the thing sure looks real enough for me.
