This is nice,but it needs more depth I think,more shading and a feew more highlights.
It looks like your doing some areas well and less time is being spent on other regions of the figure.
...take your time and work all edges man,so far so good,just practice a bit more.

Very cool model. Also, it is a very nice color selection. The NMM is also top notch, except for the black lines running along the edges. they should not be so obvious, IMO, A grey gradient from almost black to mid grey would have worked better. Very nice basing too. The claws of the hands should match the claws on the toes, but other than that, it is a very consistent paintjob.
