This is a very close copy of Akimans Chun Li picture that as an example, appears in the artbook SF20. On the very first page. The coloring seems different and so does the lines, if you just copied a picture you gotta give credit to the artist who made it originally.
Dont shy about it, or other people will just complain as I did, and it will become even worse. Just write somewhere on what picture you used as a basis.
Yah I agree With Jaysa-laser That You should totally Give Credit to The Original Artist. I mean, If no one ever saw the original they would think that its yours. So give credit. I mean this Is GREAT art. but credit is Deserved.
