I really like the colour palette on your image here as well as the simplicity of design marked by that glorious burst of a flame? Perhaps, just graphical ... looks like an abstract flame.
Humble suggestions to really kick this up a tad?
The wall portion I would have mirrored in the bottom left hand side portion. I think it would help the overall balance and anchor that side of your image ... and add to the dimensionality you have already created with the horizontal block that extends from the middle to the left hand border.
As is, and make no mistake ... I do like this ... you have stimulated my thoughts and that is indeed a good thing ... your eye is pulled to the right. Just a little tweaking and this goes from good to excellent.
