I have to start saying that I'm a former fan of dear Kevin, so I'm not sure to be 100% objective, but lets try anyway! But lets face it: it's a very (very!) good picture. I've seen loads of portraits of celebrities on Deviantart, with the feeling that yes, they were nice pics BUT... because I couldn't recognize straight away who it was, because when I saw a real pic of the star next to it it wasn't so lookalike after all, etc etc... Contrarily to that, this one caught my attention straight away, not only for the subject, but also for the resemblance, the technicality, the details... you have talent. I wish you all the best.
