All of your stocks were .JPG which made it hard for me to make a decent userbar. However, I gave my best effort and used the stocks you provided.
The Tien one doesn't look that good, I admit it. I think its because of the bad stock.
The Yamcha stock was alright, so I gave my best shot:
Even the Gohan stock wasn't bad.
As always, rep and feedback are appreciated. And thanks for the request.
EDIT: Also, if you want something changed on the bars, you're still in time.
