It's looking a lot better. The legs and feet, in my opinion, are the best part. But by "muscle" definition" I didn't exactly mean the skin--when I said the arms were too wide I meant they had no form.
Also, the arm size does not fit the lower half, man.
(Sorry for bad quality - If someone knows of a program that can capture live video screencaps, let me know)
Notice the size of his shoulders, and how his arm-width is considerably smaller than his legs'.
To be pretty honest the torso and lower half(legs, boots) are coming close to one of the best I have seen anyone do. To me, it actually resembles Vegeta, in one of the many ways he was drawn in the anime (EP: Vegeta's Pride for example, had great coloring, drawing and animation--proportions were great). The proportions of your model are still flawless in each angle, great job.
My only request would be make him a bit bigger. Screw actual heights, Vegeta looked big in that saga.
