oh that is cool. it's got a stylized look to it that's distinctive but not abstract and i like the colors too. you've got a handle on figure composition as well. Marrow is a character that's piqued my curiosity in th past year or so.
Words cannot describe. Marrow is by far my favorite X-Character. It pains me that they've done so very little with her. (I think the last time I saw her was that Age of X arc and all she did was get punked out by Ghost Rider) Good on you for not drawing pretty pixie Marrow, too!
