This picture is so great! The lineart is so amazingly clean, and I can't believe you even outlined the shadows and highlights! The way you colored this is great, and I hope you're proud because this picture deserves it. I'm a fan of the magic sparkles, and you really used them tastefully. And the background pattern looks so very cool~ What program did you use?
Lastly, your taste in manga is great. ;D Magi love!
