Thank you. I did not think of the fact that you can put it on the preview, now I will do it)

It might be better to consolidate your small file and detail file into one submission.  Just put the smaller file as the preview and then the larger file as the detail image  I know many will submit this way so they can use one as an avatar, but you still can use the preview file as an avatar while not being redundant in posts and cluttering the gallery with what seems like the same image.

That said... Very nice work!  I love his facial expression.  You have a really nice cartoon-like style.  I really can't wait to see more from you.
