Hey @GraphicsGenie
This is my entry for the contest.
Hope you like it!

Behind this aesthetic.. Do read.

🐏So the word sweater first reminded me of winter, and wearing a sweater makes you feel warm and cozy, this is what my aesthetic is based on.

🐏 So the background color gradient goes from blue (representing winter) to yellow-orange (representing warmth), that's how the pictures are arranged.

🐏So the first picture on left, a girl is blowing snow/ snowflakes, spreading all around the aesthetic, but when they reach the other pictures, they turn into golden/yellow, snow/snowflakes which again represents warmth as represented in the other pictures shown ( as sweater makes you feel warm and cozy)

🐏 As the word chosen by me is sweater, I tried to keep the sweater element in all the pictures, to keep the theme.

🐏There's also a little snowman Clipart representing winter.

🐏If you're wondering why I'm using the sheep emojis, its just because sweater is made of wool, which is obtained from sheep!

Hope you read my explanation. If you did thank you for taking out time for reading!
