I think a green bg would have worked better. It would contrast the red of the spray can, and the rose... a little better.

I quite like it

If i woulda done it... iw ould have fine tuned it a little more. Maybe have the guy twisting out of the city, from inbetween the buildings ( on a perspective or something )

And also keep the same level of detail on the foregroud as the background ( the scribbles on the wings )

But ja. That's me not you
