I like the dog it's got alot more character than some of the dogs posted.

Regarding the image size there's a sticky in the W.I.P that says they will be deleted if they are over 640 x 480. As the images you linked to to say why is he allowed to post big images, that's in the Finished work area where it is more important to post bigger images and his model had a lot of detail unlike the dog.

The rules are the same wether you've spent $250 or $5.
