Personally I don't find anything wrong with the posing and coloring per se, it's just that when someone mentions this as a "conductor", people would expect the conductor to hold the baton in a more musically-inclined way (like as if he were actually conducting a band). Just my two cents.
very nice, but the hand holding the wand, it's not natural looking. In the future try holding a marker or a pencil the way you would hold a conductors wand, this can help you know hot to draw it, aslo, I am more than sure one of your family members would be more than happy to modle for you. All in all though, the comp is great, love the lighting. and the facial expression is perfect. 4 out of 5 stars.
