The body posture is done really well as well as the lighting and shading. The depth and volume that you've given to the picture makes it look highly realistic. The texture of the hair is really well done that that it looks soft and light, like real hair and the same compliment of texture goes to the jacket and pants. The wrinkles on the clothing are more or less in perfect place, well done on that.
The texture and lighting of the face is so realistic and the features are very well aligned with the angle of the face. You made him look so handsome
The staff is also magnificent, i love how the middle part is just wisps, it gives the exageration to the use of magic. And the background is beautifully designed.
Overall, just magneficent and well done!!
