You've got Atgerm with the center image, Genzoman did the bottom left, some official artwork, and Omar Dogan did the top center, bottom center and bottom left.
Original artists , , , and some official Capcom work I belive.
The only name I see credited on this image is yours. Why is that? It's just common decency to give credit to those that did the real work. Actually, this is not permissible without the permission of the copyright holders. Want to do fan art? That's fine, go for it... but this is infringement.
