This picture could fall under any of these types of aesthetics(from most to least similar/likely):

• Adventure-based aesthetics (It is a beautiful picture or painting,I can't really tell, of a landscape)

• Time of day-based aesthetics ( It is either at sunrise or sun fall,based on the colors)

• Color-based aesthetics ( It has a specific set of colors that run throughout the picture, pinks purples and blues)

(Getting less likely)

• Nautical based aesthetics(Is missing more nautical themes like lighthouses)

• Fantasy based aesthetics( There is no Is direct connection to the fantastical but because of the coloring it could be considered in those categories.)

Those are the ones I thought of at least, It may be better to look into the separate types of aesthetics that I talk about and decide for yourself which one seems correct.
