http://1-1-7.deviantart.com/art/Direction-125740581 Not exactly the best work, but it was made from scratch. I need to work on my painting, for sure.
Looks like what would be the basis of a painting, laying down the base tones and colours. Lighting doesn't make 100% sense quite yet, no sense that the cave is dark at all. However, it's a good start, going to assume you did it by mouse as opposed to by a tablet? Spend a bit of time, just a bit a day and begin to neaten it up and add detail, refining. Good start.
It's not abstract, it's impressionist (I believe). So I don't want to see more detail added, because I like what it is right now. However, lighting is something it needs. The cave should be darker and maybe to be randy you could brighten up the beach/water/outside stuff?
