I just stumbled across your artwork on Tumblr (on there I am tomsdarling) and had to come check out the rest. You are so talented, and your Loki work is beautiful. I'm a bit in awe right now, actually.
As for recommendations, I would love to see more Loki for certain. Perhaps while he gazes down at his hand as it begins the transformation into Jotun form? I truly don't care what you draw of Loki, as I'm sure anything you do would be fantastic.
