First of all, I need to ask you “what was your goal with this revamp”? It doesn’t change the size or complexity very much, and I honestly think the original Ekimu build is more the satisfactory.
The armour add-ons as shoulders look perfectly find, as do the crystal pieces on the legs (though they feel a tad bulky to me). The chest, as others have noted, looks too big. That piece works very well on a traditional torso piece, but here it just makes him look portly and fat.
I really don’t know what my goal is with this revamp, I just wanted to build an ekimu with some extra things tying the 2016 to a and 2016 ekimu together. But I get what you’re saying with that he looks fat bit I really like the kopaka on ekimu. But, I did originally had two 5 long gold ccbs parts on the gearbox to simulate paldrens and took them out of the moc for some reason. But thanks for your input
Aside from the chubby look, your revamp uses several large pieces, creating some odd textures and making the color distribution look a bit forced. One of the things that I really liked about the original MMvSG Ekimu was that he had a pretty smooth, consistent color scheme and textures; in my opinion, mixing the crystal armor add-on and the 2015 add-on in such a small MOC is a little too much. He looks as though he has some disproportionate areas of gold as well.
That being said, I wouldn’t have ever thought to use Kopaka Master’s chest plate on Ekimu, and I appreciate the creativity. You kept some of the really core aspects of the character, and I think that it looks nice because of it.
