The sky is interesting, indeed, but i am not so sure about including this bush into your composition. The fact that it is clipped off at its top distracts me as much as that white spot which looks like a light source of sorts somewhere in the middle of the bush.
And since you did not ask for any specific critique for this photo but just ask for comments and thoughts, I moved it from the Photo Critique to the Landscape and Nature Forum, ok?
for some reason it's just showing a red x. however, i just saw the picture a few minutes ago. i was going to comment on it and now it's not visible to me
the colors are pleasant, but they're not as dramatic as they could be. i think if you mess around with the levels or curves seetting they will really set it off. the tree as a silohette etc.
if the image comes back, i'll try my hand at editing it if it's FTE
