Fine then!, Hm, The artistic delicacy seems to be more refined than the drawing of Sega, You could literally remaster the art and make it look better than Sega's art since you have a very divergently good art style and you take in details very refinely, Also the sketch itself makes the most of it, If you actually completed it, It may even be looking better, Not for you of course since this is the literal maker's viewpoint or perspective's and not the viewer's, And also, I'm absolutely sure there are some artists that's draw better than sega than then drawing sonic themselves, You have an indefinite chance of doing so since you literally might know the anatomy and the way you draw makes it absolutely unique, Simply put it, Add love and style you create gooder art ooga booga
