This is the old Ikit Claw model - I had to mod it a little bit to get him to rank up properly. But, I'm glad with how his paintjob turned out. I'm trying to take no more than a day on each of the minis from this army.
I hate to say it, but this model looks like you were rushing. While the green metal is interesting, it lacks the depth it seems you are capable of. The blending seems to have suffered a similar fate. Try slowing down and enjoy the actual process of painting - more contrast/lining between the various pieces of this guy seems to be within your skill, and could easily be done with more time.
