First, you traced these lines from a person off of DA, and even though you posted a ref, you did not post the original one, which is here:
http://akireru.deviantart.com/art/Stick ... t-50424884 and not the link you provided.
Second, right on the original artist's description, it says that you can not sell these adoptables for points (payments) of any kind since it wouldn't be fair to profit off of their work.
Locking this thread, please go over both the CS rules and, if using a free line-art, the original artist's rules before deciding to sell adoptables based on their lines.
