I'm surprised that I have not seen this moc before! Your self moc is epic! I like the overall complexity of his design. Especially in the legs. [The rest of the comment you can skip if you want.] For my self moc I am currently getting the parts to make his arms, finish his legs, and the other half of his torso. In the end I'm making him as as awesome as I can for his size, of which will be at least 16 inches tall.
this is outstanding! id have to say, the legs and torso are the best parts of this MOC. i still cant get over how well the legs work. they seem very detailed. my only complaint is that the upper arms are lacking mass compared to the heavily armoured torso and legs... aside from that, this is very very good. ~JP
my honest opinion is that everythign but the arms are amazing. The arms are too plain and are weird in my opinion. This moc is amazing though ! Great job. 5/5 BTW: i now envy you because you have soo many orange pieces. Just joking.
