This looks like an 9-10 for me, but I can only guess. Hurry up put it in in a larger Picture!
But a 4 for this ist just stupid, sorry to say that so harsh. Even it is small you can clearly see its a very good painting job and not below 5. Silly.

Im sure its a good model, unfortunately i cant really tell as it the pics so small. Try 400x400 pixels with just one view of the mini at first. Also remember, CMON resizes width. So make your images vertical, not horizontal
