Cool! A bit muddy, but a highly effective and ambitious piece throughout , I like the fact that unlike most entrys the axe has proper foreshortening and is not just an obvious trace over of the reference. The posing here is also challenging, and feels like you are in this to get better. That said you should make the investment to get some better PS brushes, the default brushes don't work well for the style you are going for.

SOOO cool man! Good luck!!
