Good work for your first mini, some advice to improve your next works:
-Highlighting & shading can give a mini more life. For example, if you used a light grey wash on the robe, and then applied white to all but the deepest recesses, it would give it more definition. This applies to every other part of a mini as well. Still, the paint is applied very neatly, much better than my first mini! Keep up the good work ;)
One important thing to remember about digital cameras is that they tend to be better than 600 pixel maximum requirement for CMON. Taking the photo and cropping the photo to a 600 width size will avoid the file compression that CMON normally performs on images over 600 pizels wide. With that having been said, there appears to be no flaws in the mini itself. The mini is somewhat plain to rally have any complex detail to judge on, so one is attracted to the robe, and the lack of highlightw and shadopws on the robe. Because of the small size of minis it is somtimes necessary to eggagerate those shades and highlights slightly.
