Magician Tribute v.2

The positions and poses of each magician seem to be in the right spot.
I also like the facial expressions of each one, although the red dark magician (the one used by Arkana) could had a more sinister look like his debut in the anime: baring his teeth and his eyebrows more evil.
The colors r great and well shaded, however, the magician in the front needs to be more shaded and, in overall, all the shadows need to be more contrasted with the basic color.
Also, do not know if this would be necessary but the plain white background wouldn't give the big impact you're trying to transmit. maybe a magical background could help you out.

Concluding, despite having some small errors in the details, i think and consider this a very great magician tribute. you captured most magicians in a very good perspective. and now i say:

Keep up the great job you always do.
