Dark Star Mordekaiser

A couple years ago I saw Malicious Metal made concept art for DS Mordekaiser and Vladimir. Seeing his post made me want to make my own version, and so I started the next day. It took me about a year in total to make this concept, but I finally finished it a week and a half ago. This is my very first concept art for something, plus I'm not very good at shading (I almost always use flat colors) so it might look odd.
