Lets see, compared to the existing characters in SRB2, The scale of the head is far off. For instance, if you were to duplicate Tails head across his entire body, it would fit almost 2.25 times, which comparing to this, with a head scale of 3.5, seems a fair bit off. Second, it appears to have next to no shading what so ever, except for the colored outlines, which in a game with far less colors, would actually be somewhat decent. Third, and above all, which may be the most glaring issue of all, is that this character does not exactly fit in with the apparel of most female sonic characters, whom the clothing of which tends to more... simplistic designs. That is all.
