im normally not a fan of HDR - sometimes i think people only use HDR to make bad photography look good. But here i think you have it spot on - and its what HDR should be for. it doesn't look too fake or too altered and the sky is perfect... i think the only gripe i have with this is the light area on the left - is it possible you could tone it down slightly - my eyes were drawn to that area instead of the rest of the image - but i suppose everybody is different maybe you dont think the same. - and maybe the black gate - im not what the frame would look like without the gate - do you have another version at all?

but overall i love this image - great detail in the background to th e left of the ship and the sky looks great
