Do not assume others know anything about a character when writing his SU, as that's not the point of an SU. I want to see that you can accurately describe him. Last I checked, "Insert pictures of Ash here", this hadn't been done.
Oh... Well, to put it bluntly it's not properly filled out. Because of the serious risk of crack an application for a canon is actually more strict than that of an OC, because you're expected to be able to play them "well".
