The idea is very creative! Though it isn't very original, I like the "story" in it. The fires are very well-drawn, though a tip would be to perhaps draw fire on the buildings as well, like through the windows if you drew any. I like the glow as well; it gives you a warm, fiery feeling.
The buildings are okay, I like how you did the cracks, but I also think that you could have drawn a bit more details on them, such as cracked windows and burnt doors (of course, they don't have to look like that).
The shading was done really well, and the character does seem to show a bit of "emotion" the way it's positioned (I also like that little yellow collar thingy XD).
Overall, I think you did a fantastic job, and I hope this critique helps! ^^
