First thing first, I love this! I feel all warm and cosy inside! And it reminds me of a sky I saw few mounths ago, it had similar colors like this one Not to mention one of my favourite songs called Blood Red Skies by Judas Priest.
Now let me explain why I rated it this way.
Vision: since in some definitions vision is something abstract, something artist can see in his/her own mind, I can only guess what went trough your head at the moment of taking the shot and because of that I can't give you less that given. Also, I can guess that you were amazed by the sky and I can't blame you - it is amazing
Originality: I had to rate it with 2.5 stars because I have seen many sky shoots similar to this. But don't let this bug you, I didn't meen anything bad. Keep in mind that no matter how everyday they might be, awesome sky shots can leave great impact on someone.
Technique: The colors are well balanced, I love how they go from darker to lighter, harder to softer, sharper and dull. And the dynamics of clouds is amazing. And I see nothing at the moment I would change.
Impact: YES, 5 full stars because it's just awesome. I said it at the beginning but I'll say it again: it makes me feel warm and cosy inside! The clouds look so soft, too bad my bed is not like that xD
All in all, keep up the good work, you have some amazing peice of art in your gallery and I'm looking forward to more stuff from you
