I think you are a little to critical of yourself (although I’m one to talk).
Your work is excellent and your likeness of bale is passable, I could tell right away that it was Bale.
Your texture composites are very good too, they seem to have created an oil painting effect.
As far as borrowing from other artists we all borrow some thing or another and studying others work is an excellent way to develop style, not to mention it pays the other artist the highest compliment.
