How can you even critique an image like this its brilliant!
Ill give it a shot, but I think you already know you have a fantastic image here.

Compositionaly its centered with just a touch of weight given to the right by the direction of the lightning bolt as it travels upwards.. it works for this photo. the off center horizon emphasizing the clouds works as well. Although part of me wishes we could see more of the reflection of the lightning in the foreground. Being able to see the two side bolts in the water would be very awesome.

Judging by posterization in the oranges and a few stars
showing up its obvious you used a higher ISO. On the right side of the image above the cloud its especially apparent and hopefully with a bit of selective blur can be cleaned up. See if the noise can be brought down some, the image given to us is small but its apparent even at this size.

All summed this is a powerful photo, and is awe inspiring; bravo and great job!

first off, this is MAGNIFICENT. _{[i've been using that word for anything compared to the storm.]} but actually, it's a picture worth a million x 2 words. it was timed perfectly with the flash of the lightning and the intensifying, electrocuting streaks that branch off from the main lighting strike. i love the way the sun and electricity light the under side of the clouds, and the fact that you look at the top of them, and it's dark enough to be midnight. this photograph was taken at the perfect time with the precision of seconds and minutes of the sunrise/set. The grass also adds a very individual vibe to the picture as you see reeds of solitary plants that show the individuality of the setting with the fantastic use of lighting.

i wouldn't call this an exaggeration. i absolutely LOVE it. ♥
