I haven't seen the original so I'll go only off of this one.
The build is rather shoddy, the torso is just an extended Inika torso, but it's not bulked up enough so it ends up looking awkwardly lanky, if you want to go for a lanky look then go for it, it just needs some improvements.
The upper arms are the other awkward part, they're simple and affective, but I'll suggest this minor change, make the axel that connects the claw to the upper joint a 2 long to get rid of the unneeded bushing, replace the connector on the back with either 2 axle ones so it wont move much, or 2 thin liftarms, which will let you add stuff on there, if you're not gunna put armor there the style you have it now will look more complete and clean.
Lastly, put a Visorak foot on the front or something, to cover it up and make it look more finished.
The colors also need a lot of work, blue and green can work fine, it's just how many different shades and their placement which is causing the problems.
There's 3 blues and 3 greens, although there's very little dark and bright green, just lime.
You've got blue hands and feet which is good color blocking, but then the entire upper leg is trans medium blue, and the strange glow in the dark stuff from takadox.
The lower legs are dark gray, which shows up no where else, but it's got silver on it which is a step in the right direction, I'd recommend making the upper legs less blue and having some lime on them, and the lower legs blue with silver, but you should also try to make them thicker or something, unless you wanna go for lanky, custom builds are always nice.
All the lime is clustered around the top, which could look good if it was more spread evenly and the other colors were better, so either spread it out or work with it.
As I already mentioned, the arms are fine.
The torso is what really bugs me, I just don't like the look of it or it's build, and the green bit on the hips isn't needed, should just be a straight beam to the upper half.
And I really don't like the lack of coverage and the small chest.
Also you're gunna need more light for your pictures.
Don't let this harsh review get you down, I mean it all in the best of ways.
