Haha, first off...that dude has more talent put into that hydrant than you do in all your work, because he's obviously a professional 3D artist. Second, go ahead and attack my work, it's just a hobby and I have a brouder spectrum of "art" than you do, because as I can see all you have is some pictures of cats and a leaky hydrant (that you borrowed.)
All my work is original or at least credited to the proper persons. If you made a mistake, then admit it straight up, don't come on here trying to defend yourself by insulting other peoples abilities.
Next time draw your own damn hydrant.
