I love the Color! This photo has a strong impact, as soon as I saw it I had to open it to see it better. But now I see some errors. I can give you some advice: The cut of the picture is not adequate, it would be better if you apply the rule of thirds (search the rule on wikipedia) and the horizon must be straight, use a ruler to check. Another thing for post-production. I see noise on backgroud, I like more nauced's sky
I hope that I helping you with my critique, the photography it's an Uphill Climb, the best thing that you can do to grow up it's see a lot of good photos of good photographers and here on DA you can find these photos!
