Oh, Un’Jaguk what happened to you. From a regular Toa build to a messy titan form.
OK, first of, the overall look is disturbed by a few things. The colour scheme is inconsistent: the guy has tan legs and torso. One of the arms is light grey and the other one is gun metal. The gun metal grey needs to be replaced, mainly because it is found exclusively in the arm. To continue, I would add more tan in the arms, especially in the upper arms. The other thing that is disturbing the view is the fact that those shoulder panels are just out of the place. They are sticking out too much frontwards, and are placed there in a pretty awkward way. I am pretty sure that those are interfering with the arm articulation. They are also too big. Like way too big. You don’t make a titan by just simply putting some big shoulder panels. They also brake the proportions. This version of Un’Jaguk suffers of what I call ‘The Axonn Syndrome’. Some parts of the moc (the arms and the shoulder panels) are way way WAY too big compared to the rest of the moc, just like Axonn’s hands and feet. As I said, the proportions are kinda killed, but not only by the arms, but by the legs too. They are too short, compared to the rest of the moc. Make them longer. And what is with the trans-blue and with the red?
The build is a pretty standard CCBS titan build. Nothing too special or too bad. As I said, I really dislike the way you attached those shoulder panels. I also dislike the hand design: the hands themselves are tiny, and he fingers are gigantic. And clawed. A Toa does not have claws, man.
And now the backstory. I can digest the fact that he was turned into a ‘Toa’ by a Mask instead of a Toa Crystal, but I can’t digest the fact that this build should be a Toa. This is a Titans. The Toa can be Titans, yes, but as far as I know, there are no Titan sized Toa. I may be wrong tho. Besides this, he does not have the usual characteristics of a Toa. He has claws, horns, a skull face, spikes armour, etc. He reminds me more of a villain than a Toa. And finally, the Element. Un’Jaguk should be a Toa of Metal, but Metal is not a cannon Element. Iron is. And the colours of Iron are orange and yellow. Yes, you can replace Iron with Metal and orange with tan, seeing that this is your universe, but I am the cannon fanboy of the site, so I had to bring this up.
Over all, I am not a fan of Un’Jaguk being a titan, especially seeing that he became one with not training or worthiness proven from the past actions whatsoever. 8/10.
