I don't think you can legitimately state that there are mistakes in any piece of work when you don't know the artist's intentions. But I'm sure you feel more comfortable speaking from a position of illusory authority.
I think the piece came out well, and it made the customer happy which is the most important aspect in a service transaction.
Artists intentions? Please miss artist...tell me what you were thinking when you drew, penned, and colored this piece?
Anyway...
1) was it the artists intent that the hat and cloak faced the viewer instead of being centered on the character itself?
2) was it the artists intent to not only miss out on the adams apple but also fugger up the neck and shading as well?
3) was in the artists intent to avoid proper anatomy and perspective? (the positioning of the character is all wrong, including left foot to left knee...left hand...neck)
4) was it the artists intent to *hide* the left pony tail down the shirt without showing a hint of it again in the crease of the collar?
5) was it the artists intent to put the skirt OVER the robe?
6) was it the artists intent to have the right sleeve up left down? Physics would dictate that a counter clockwise rotation would have the opposite of *intended* effect.
7) was it the artists intent to give no illusion of a right foot?
8 ) was it the artists intent for the char to focus away from the viewers main focal point? It would appear to me the left hand is a point of focus for the character...why arent their eyes matching this viewpoint too?
