I must say that this is very impressive work, it strikes as actual offical art from SEGA if they were to make Sally Acron appear in a Sonic game either based off the Archie comics or just in a Sonic game in general.
As a fan of the Archie Sonic universe, I must say that this perhaps the best fan-art 3D model of Sall that I have ever seen. It really brings Sally to life as a Sonic character, the texture and detail is excellent quality. The best of luck to you in future artistic endeavors because without art, where would we all be? Keep up the excellent art skills, you have serious talent.
