I don't like it.
Technically, it's a good piece. The dark, smoke like background brings out and renforces the idea of the flame burst. The colours of the flame are well done, making it look like a real fire rather than a child's attempt.
However, I'm not a big fan of the shape of the flame, though thinking about it it does look a little like the Fire Blast (I'll google that later) attack that some critters have. I realise this is an abstract piece, but the total shape just looks a tad too odd for me; I think it's the slight curl attatched to the upper left arm.
The colour of the text looks slightly too pinkish - and I know you love hiding the text like this so that it doesn't overpower the picture, but I feel this one is a little too hidden.
I can't really say what would make it better, beyond de-pinking the text, perhaps using a slightly different font, to better join with the idea of 'abstact' (a serif font doesn't really do it for me) and slightly changing the flame (so that it looks a bit like a katherine wheel gone hideously wrong?).
For the most part your work is very good compostion wise.
