Great composition and subject matter. Lighting and detail are good, rich in color without being over-saturated. Good timing on the shot with the lighthouse being lit that way. ((8))
So strange clouds, I always loved strangeness of the nature. The composition works well, the storm is menacing with these colours, and I love the light on the top of the lighthouse. Though, I still miss something that I can't explain. I tried to hide the upper 40% and this way I felt your photo a bit more balanced.
it's not bad at all - though I'm not sure you've made the correct decision about your cropping: whilst that bright band at the top of the image should serve to emphasise the darkness of the clouds, I think it is unueccesary - as the contrast with the lighthouse serves that purpose anyway, and that build-up of cloud, and the red under-lighting, would be the more powerful for istting in stronger parts of the frame compositionally. More than anything, i think the file size of the submission lets you down - you've used around a fifth of the avaiable file size, and that's severely restricted your level of detail in such a large image, and detail is important in such a small image size as we get here.
Nice photo, definitely very moody and dramatic. I would have cropped out the top of the sky, and left the dark gray at the top of the image. Just my opinion.
