Awesome work man! But I may or may not have some advice.
Rhyse? I think it was..(I spelt that wrong): He looks like the best and you can tell that your SelfMOC was made to be your crowning jewel. but I think he could be touched up (just a bit)
1; The bulky torso is fine, but the way it was done may need a bit of work. the armor you used does not flow from the chest to the middle of the torso. if the silver is meant to be extra armor, then maybe move it up a bit. like make Takadox plates silver. and try to make that area be more pronounced. and the Nuparu marhi armor needs to be replaced to make him look a bit thinner, unless that is how you want him. and if you are making the Takadox plates silver, then maybe make the Metrutoran armor dark blue. and he also needs to have some of the trans colors removed, and you can do that by following my tips given above.
ToaOfUltimateDoom: he is simple, just like the real one. so I will not judge. but maybe just greeble him up a bit? I dunno... here is my critique..
1: His torso, the Bohrok eyes kinda stick out funny and if you can, fill out the holes in his arms and legs.
Vuhii: now I like this one, I really do. the scope is nice and the CCBS arms work well with the legs. on to the bad part.
1: he looks kinda....squished to be frank. I always see Vuhii as tall and lanky. this is short and bulky....so yea..
Waj: He is a pimped Metru build, that is fine. and I really do like the way you gave him armor on his stomach. now to the pointers.
1: Colors. he needs more black...that is all I can think of....Maybe more trans blue? I dunno..
BeefJStag: he looks fine and really good! I enjoy his overall look and just...I really enjoy him. now...to be mean.
1: The chestplate looks a little off...and I have no clue....Awesome work on this one!
Jason: he is my least favorite of these MOCs and I will explain why. but as for the pros....he looks like a good frame to work off of...now to why I dislike him..
1: His colors, they are really random and seem like you made him with leftover parts after making your SM. he has Dark blue, gunmetal, baby blue, bright blue, two trans blues, greys, black, and silver. cut out half of those..
2: his legs. you say he is a big Halo fan? well maybe give him more of a spartan look with his armor. the legs look really boring and plain...
3: the arms. the lower arms are okay, but the CCBS does not work with the rest. and the upper arms are screaming to be armored. the one hand I find okay, if you mount the gun better.
4: the torso. he needs to get that gap in the middle of the Inika armor filled. and make his torso seem more like it is attached to the rest of him, maybe by filling him in.
MaximumWarp: He is amazing, one of your bests. awesome work on him overall...no complaints.. other then that the mask looks kinda out of place.
Nyran: he looks pretty good, a little dated next to Matt and you, but I think he works well, he looks simple and clean. nice job! but I have a bit of stuff to say.
1: The arms. the upper arms are fine, but the lower arms are really skinny and look weak.
Oculus. he is almost perfect. except there are a few places with holes, a stud should fill them in. but I have a issue with the lower legs.
1: The feet. make them silver, or change them to a different foot.
2: The lower legs. they look.....flat? plain? boring? maybe just rework these completely.
Slime: he works well. I only have a issue with his lime spots.
1: the hands, they look too robotic for a being made of slime. make them the CCBS hands, they should work.
2: the face. see all of those open studs of his face? take some lime plates and fill them in. it will look a lot better.
Pot8o: he works really well! a few touch ups and he will be set!
1: The chest. it is gappy and strange, the color is also off.
2: take the white spike off, I get the real one has white, but that does not mean that one little spike on this will work.
So... those were my thoughts....take them as you will..
