Great job, never thought yo would get the legs so accurate, best mech model I've seen, period.
As for the influence of ESF on MechMod, there are a couple members on the MechMod team that are on the (or were) ESF team or DMZ team as well, like pcJoe, Shijing, grOOvy, Jason etc. I don't see why it would be bad for them to take some parts or ideas from ESF, seeing as how a lot of the team IS part of ESF, or helps it no less.
