First of all: i like the Idea. No artist truly works digital or traditional, most workflows nowadays contains at least some sketching or internet research and I like, how you conveyed this Idea by blending screen and desk...
And I like, how the colors drip out of the screen onto your paper.
BUT this is a critique so here are things, you can improve (And don't worry, that there are more negative points, that's just me, I am bad at telling people, why I like stuff and great at telling, why not. ^^);
-Composing: I am not good at this, myself, but I think, that there is a lack of a clear focal element. I think it's this strong, red blob, that draws a lot of attention from the less saturated tree and you might want to improve on that.
-compositing: The blending of digital drawings and the real elements couldt be improved...
-Contrast: crank it up a little bit :D
(And btw I had a kind of similar Idea ... you can check it out on my account, if you're intrested ... and i'm not telling you this, because I have a new account and in need to get scouted in time to be able to participate...wich is a really weird system)
