I don't know what it is about deep sea diving, but I think it's bone chillingly creepy. This is double true for investigating sunken ship wrecks as these two divers appear to be doing. In any case, great piece of art thanks for sharing.
My first impression of this was definitely "underwater", but when I clicked and got closer up i was like "oh wait, no, it's on a snowy mountain or something." The wind-like lines and flecks give a feeling of air. Another things that I think is contributing to that is the fact that there is a light fog-like effect towards the bottom. Generally water gets darker the farther down you go. The same thing normally happens as water goes back into the background. Also given the lightness of the picture as a whole, it doesn't look far enough underwater for ships that large to have sunk, though I may have no idea what I'm talking about with that one. This looks like atmosphere obscuring the view rather than water.
In all seriousness though, i quite like it. The color choices make it stand out nicely, although the "currents" make it seem more like wind than water flow. Nice touch with the figures. Is this supposed to be a ship or a rock formation?
well it was supposed to be some kind of ship wreck, at least that's what the speedpaint challenge was called. But turned out not as clear as i wanted after an hour, probably why i kept it and didn't post right away
