Very nice. I have nothing to add, really. There's some stuff, but since you obviously did it on purpose I'm not going to criticize.
I like the light in the first one, it looks like a fire, but the context is wrong so there's some ambiguity there -- is it a fire in a semi-urban setting, and if so, what's up with that? if not a fire, what?
The second one is a great evocation of mood, with almost equally interesting light.
The darkest regions of both are very well handled.
