Since you asked for my review of this texture Shido here it is
So first of all, I think this one is amazing; similar to your other work you've taken a unit that AFAIK I haven't seen many textures for and done something very different and cool with it. Particular kudos must be given to the details on the faces and the glowing orb parts which look phenomenal. Again, your texturing style is very bold and cartoonish which I think is great and not something I could replicate with big, bold colours and blocks of colour (in a good way).
If I had any nit-picks to give it would be perhaps the blending between shading could be a bit better, make the transition a bit smoother for example on the green bit of the "tank" and on some of the grey bits I think it could be a bit smoother. Another nitpick would be the arms and hands look a bit bland, I think you could add a bit more detail to them. Also my final nitpick would be similar to the centaur texture, don't be afraid to use the darkest colours in the recesses, make them dark and bold and then use much lighter almost white bright shades on the highlights. Warcraft models look really good with bold contrasts between highlights and shadows and I think its something you could explore a lot more without losing your iconic cartoonish style
So in conclusion, I'd give the skin a 4.5/5 with a 5 with some slight improvements to the arms, hands and smoothing the shading a little.
