heh, good luck, that zaku prototype is a tall order to hack build and scratch build. Also, not to nit pick, but you forgot to fix your seams on the claw arms
Not bad but! I see some seam lines on the top cannon, middle side of the pitchens and your weather could use a little work. Also some work on panle lines. On the good side over all it looks alright and the battle damage is spot on. Keep at them and happy modeling...
