Theres BG on alot of these and it looks like you need some help with rounding off edges because I see some of the transitions are off and there are choppy parts
Keep posting your cuts though, guys will give you help
Some you feather, you have to stop that. Even if the cut is really good, feathering will kill it. Also a lot of you cuts are choppy, if you are using the pen tool, bend your lines more and make the points closer together.
I would say yes if you fix them up, work on rounding edges and don't feather. The only one I think that can be added as is would be the Jason Campbell cut, maybe the Rasheed Wallace cut too?
My suggestions:
1) Do a black and white fill under the render to see if you missed any BG.
2) Stroke your render, before you post it, to see if it has any rough edges.
Of coarse, remove it before you post.
