Why no comments?? O.O
Technically I think it's very good. The vectoring is nice and detailed and soft. Some lines look a tad sharp in some areas, but hey that happens to everyone. XP I think his eyes are a bit too brown and should be more golden to be more true to his character design. The sky could also use some other color, like violet near the top, cause the wall is quite monotone in orange/red. Lastly, I'm not sure about the text, especially the Coldplay lyrics. Hmm Somehow I feel they don't fit, but if you like them then disregard what I said. XD

Before I start the praising, I'll just point out the only thing I dislike: the huge, blended 'Let it Out' text.
I really like how the wall looks with the rest of the text, it fills the background nicely, complimenting your amazing vector.
So, I think you should either let the blended version of 'Let it Out' or the clear, maroon one.
It's still a very beautiful idea, extra congrats for making such gorgeous eyes < 3
