Very nice work man. I really like it. I personally like the Timber Wolf original better but this is a very nice reimagining.
If I could bring in a two bits of constructive criticism one would be to not forget the scale of the mech. With the cockpit as big as it is this would make the mech as big as the commando or have such a huge window it would be crazy. I do like the window but its just a bit big for a 75 tonner in my opinion.
The other is about the missile bays. they do look a bit off in that they are pointing to port (the left of the mech) maybe you could fix this a bit by not making the top and the bottom of the pod parallel (like the starbord pod) and maybe tilt the face of the pods back to match the body of the pods?
I hope this helps but definatly keep going because its awesome. I really like it
