no offense; they are good edits in general. The problem really isn't with your spriting itself, but I would have to say you do not meet a rather black and white criteria; you have only one view. You must have an up, down, left and right view. Perhaps I am mistaken, but I believe that was a requirement. That would really suck for you to be disqualified, but nonetheless, it would not be fair to the others who not only met the requirements, but also involved a lot more custom spriting than your sprite.
I am surprised that this has gone through without any comment. Perhaps I have missed something, and this was explicitly allowed due to the low number of entries. But your sprite should still stand or fall based on the effort put into the sprite. Now you may have worked hard, but not even an attempt at other views seems kind of lazy, in my opinion.
