And I suppose you are a master artist who never had to learn? Everyone starts out weak and grows with experience and constructive criticism. A simple comment (which had already been made) about the reversed hand (a very common error hen learning) or some useful advice would have been in order, not a fool's 1/2 cent nasty statement. It's always better to keep your mouth shut unless you can do better? If you are such a hot artist let's see your version of this drawing. When it does not show up within the week then everyone will know you are just talk and no truth. At least the artist posted, which takes a lot of courage when still learning.
Also, if this is the poster's own work, which I can't be sure it is since there's no artist or source, it shouldn't have been posted. Posting your own art is frowned upon.
