You fools.
Read the damned description. This is commissioned work. The artist was PAID to draw this for the cover of something. Rating it down because it features someone you don't like is the act of an idiot.
Reviews are to rate and tell what was done wrong and how the artist can improve. You can't really tell someone to stop drawing what they want to draw, and you especially can't tell someone to stop drawing something they're getting paid for. Reviews aren't for content so much as for execution. And frankly? This is excellent work. It's an excellent representation of him that's very realistic looking, detailed, well-painted, and even still keeps some amount of stylization. The color scheme is great and the added effects are awesome as well. My only problem with it would be the amount of blank space near the top, but, since this is a cover of something, I would assume that's where the title will go.
Keep it up, sir.
