any feedback is appreciated

Your anatomy is strong, which is good. At least you're past the hard part.
Some things that need attention:
The coloring is very gradient-styled. This causes a flat look, and takes away from the 3-dimentionality of the character. Adding some more solid shading will bring out the light source and properly define the figure. Check this out for some excellent ideas on coloring and shading. It has some advanced ideas, as well as some beginner basics.
The lines are a tad too thick. I mean, thick lines can work, but only if they don't crowd the anatomy and make the figure look like a big bundle of lines. With a little toning down of the line thickness, you'll have a professional looking piece in no time! ^_^
Keep up the good work, and post again soon!

very nice only he look's kinda angry
thank you very much for all your comments. Hehe he's supposed to look angry, he's supposed to have 'attitude', heh
I guess it's too obvious which part I need more practice with. I will look at that link right away, I'm a bit lost how to do colors without using gradients (and not using it very well).
The lines were a bit thick, because I was having a hard time cleaning up my pencils and cheated a bit. I need to work on that as well.
Totally appreciate the feedback, it gives me a better sense of direction for improvement.
Proportion-wise, it's lookin' good. And yeah, you already know, but having thinner lines and adding finer details would greatly improve your works.
You should also practice foreshortening. Mastering foreshortening will really make your works stand out from a lot of other works
