So, this is a yet-to-be-named MOC of custom element. What I intend to change is the eye-color (black as of now, will be blue), The dark tan on his shoulders will be replaced by silver once my bricklink order comes and lastly - I will try to fill in the knees a bit. I might also consider ordering custom hands from shapeways.
Anyways here is what I have so far - both criticism and praise welcomed. 
This looks pretty good. I think that the silver armor on the torso is a bit short. I would also like some pics of the back.
The dark tan needs better distribution (assuming you do end up keeping it) and the gold/translucent yellow is out of place.
Also, the upper chest is very bulky for a rather small pelvis and very long, sleek limbs. And I am sorry, but that piece doesnât work well as a pelvis on this MOC.
The red balljoints should also be replaced.
Just one other thing, I think you should give a MOCist credit when you use their foot designs.
The waist is disturbingly skinny.
Trans yellow works with the torso, also needless to sayâŚitâs a golden mask.
This is blatantly obviousâŚyour are basically mentioning something most people would do.
what? Whoâs foot design am I using?
I wontâŚI said it will be replaced with silver.
That it is - we shall see how well I can armor it while still keeping it mobile.
Just because it has story meaning doesnât make it any more coherent 
If itâs really that obvious, then maybe you should have included that in the list of things you plan to change? 
Itâs a design that (to my knowledge) was created by @Alieraah.
I meanâŚthose are pieces that shear the same colors with red and blue pins, obviously those are going away in the final product. 
Thatâs trueâŚbut it is the closest I have.
I will check it out, either way - I was not aware of that. 
Also, is this MOC a male or female character?
2001 had plenty of tan masks if youâre looking for something with matching colors
The waist is gappy, especially if youâre using that piece to connect the hand. Iâd know, since Nexus has a similar problem.
I might bricklink tan Huna. Anyways, you are rightâŚone of her MOCs has very similar foot designâŚeither way - it was not intentional.
Itâs okay, the obvious open technic sections are odd, but they seem to fit in. It looks like it could be improved at the waste, and maybe change the red ball joints to black. Otherwise, it looks pretty good so far.
already addressed above.
Sorry, I donât see any âwasteâ on this MOC - you must be thinking about waist.
WellâŚcustom torsoâŚwhat you gonna do? I will change the Technic in the torso to full black and we shall seeâŚ
Maybe adding smaller system bits for âfine tuningâ may help to cover those areas.
I think System might make it worse.
Yes, I meant âwaistâ I was in a hurry and forgot which homophone I was using. The technic sections, I meant on the legs.
Canât say Iâm bothered by the legs how they are right now + the Technic stands out only when they are not in straight pose.
Perhaps not system, but something similar.
Just little small bits to hide the exposed technic.
System canât make things worse. 
In all seriousness just using tooth pieces would probably help fill out gaps. Or Exo force arms.
call it Duna, Toa of Sand
also nice moc, I donât know how to feel about the hand in the hip and the red ball joints, but everything else looks pretty cool
Onhestly, the shaping and everything leads me to think this MOC is female.
+1 to female characters outside Ga-matoran
And I know that feel when you only have Red balljoints left.
As a word of advice, maybe add some Burnt orange as shoulder armor and the shell thatâs holding the chest on, to not have the mask stick out as much.
