Resurface

I like this a lot. It's an interesting concept, I've seen something similar but not this detailed. However, I do have a few things to suggest.

First off, what bugs me most is the reflection of the fingers. To me, from the angle that the viewer sees, I think that you'd see more of the bottom of the fingers than the nails. The thumb bothers me most in this regard.

Secondly, I don't quite think you took the liquid far enough. It seems like only a small part of the image is used for the "surreal" aspect, and the rest is boring. I do think that the overall technique is great, much better than anything I can currently muster, but it seems a bit limited in terms of the imagination.

In a few words, I think that you did a great job on drawing the image, but it seems to lack in imagination. It was a good idea, but you might try making it a little more colorful, making the surreal parts of the image stand out against the tablet or the normal surroundings.
