when i saw this situation it made me want to listen to a song by 'Apocalyptica' (a sweet metal band that is comprised of 3 chellos and thats it... beautiful music....) anyway this picture does the same for me... love it... gosh!
OMG! It's like day and night are mixing up toghether. I don't know wich I like the best. Day colours are optimistic and calm like the light blue (top of the picture) and sunset ones are passionate. I think it depends of my state of feeling. Now I feel calm and optimistic . Anyway great job you've done!
