Cool
First off to answer what Relmyna couldn't figure out.... its the eye leading quality of the piece.... it doesn't flow very well from one person to the next, plus the unorthodox positioning of the red coated figure and the vampire character makes the eye want to lead away from the other character. There is almost nothing to lead to the character a bit further away as well.. Like going from the girl which is the main point the eye immediately gets led to the guy in the gray shirt.... but he is pointed away which draws the eye away, that could be fixed by say making him hold something - a giant candycane perhaps, that is pointed towards the red coated figure.(The ring going around isn't noticeable enough to draw the eye because of how the characters stand out, [more the way they can lead the eye EVERYWHERE cause of pointed hair and such, the antlers the most noticeable], I had to look again after starting the review to notice it went around).
Lol ranting as I am other than the problem that I pointed out it is a very nice piece. The characters are well designed proportionately, and the only other advice I'd give is to maybe blow up the character in green a bit to make him feel as if hes actually in the group.
