First off, great stuff! Clean shot with your phone. Good set of colouration, warm colours dividing the focal point from the landscape. The heart cloud is put a third of the overall picture, well done there instead of typical central shots. Pretty even landscape with accenting trees on the opposite side of the main cloud mass.
I'm glad you chose not to include the sun as it would have overpowered the shot of the clouds. The lights are a bit distracting though you can't exactly turn those off. XD I liked the blocked out sections in this shot, we have the black silhouette of the ground and trees, then a block of colourful clouds, and then a pretty neutral sky to top it off.
Great job! Looking forward to more.
