I had mentioned to you once before that your photo series that incorporates existing graffiti is quite striking and with this one you continue the trend.
I like the humour in this one and the model fits perfectly in that his mouth is not open wide enough to catch the full drop of ice cream which would cause it to splatter onto his face. That small detail whether intentional or not, enhances the funniness of the piece.
As far as colours go there is no denying that the graffiti just pops here due to the muted surrounding colours. However, I find the jacket of the model to be a bit too dark since it blends a little too much with the background.
I do have a small nit-pick with this image and that is the slight skew to it. The lines of the boarded up window lean a little and aren't quite straight which I find distracts the eye a little and breaks the symmetry between left and right (if one was to look at the white pieces on either side of the window.)
Still, this image gave me a chuckle and it is well executed and the skew can be fixed in photoshop if one so desired. Keep up this series, it really is remarkable.
