Mmm

That’s a rly smart and calming compostition

I’m guessing the line is an airplane?

So i think you could curve the mountains so they also go around the circular compostition

Like the 2 sides could be higher

Also, maybe make the scenery more yellow and brighter, to make the lighting more interesting and contrasted

Eg. make a glow/shadow on the clouds
