ok..the above image is a Mech from MAss Effect..ours are a cross between these and the Exo-squad green one that the COMs guy used...I looked at 1000s of mechs and armor, but none are my versions ( whiuch makes sense I guess?)..even the 'real Mech' witht eh chick inside at a Tech Con was a bit too big.
I will try and sketch one sometime and put it up...but this gives you an idea of sorts.
