Hello Laura, I love your designs, they are different, bright, colourful and sexy! As a first impression, nice everything, one think that needs work is items titles, try and read stuff about etsy SEO
for example, this (very nice) illustration
https://www.etsy.com/listing/496302075/cowgirl-exotic-fashion-illustration-art?ref=shop_home_active_...coluld have more keywords, like Woman Print, Red Home Decor, Erotic Art, Sexy Gifts, Woman Wall Art etc
Try to use phrases and not just words, like "Home"or "Office"
Good luck :)
