Oooh. Would definitely like to see where this is going. The visuals of Mert's magic's physical manifestation are quite nice--I especially love the one about the dark drops of oil refusing to blend.

I rather like the idea that his magic appears to be bent on destruction, too, and that he has very little control over it. Also, there seems to be this sense that it's not just a force he has to learn to control, but an actual sentient being of some sort (almost like he's sharing a body with it, and reluctantly, on both ends of the relationship).

For a rough draft, I quite like this. There are a few little bits that could do with some light editing, but that's for later, after the draft is more complete (so you can catch the nuances and work with things like foreshadowing and identifying themes and such as you do it).

I do hope you continue this--I'd like to read more!
