My only critique as somebody with no artistic skill is the sky seems a little too empty or there's too much of one color. It's a perfectly realistic color for the sky to be on any given time of day, but I think if you experimented with more of a very subtle gradient or maybe have it set in a later time of day where one side of the sky would be off-color or slightly darker than the other, it wouldn't feel like all washed out. On the top right corner, I really like how you did the clouds though, those feel really natural like they belong there
