Those patterns! Well done

this looks neat
but i just couldn't help myself and so i have to give you some constructive criticism

this is a common mistake for a lot of artists but try to desaturate the background a bit

also, the bright blue sky is okay but you should try to shade the leaves in a different way like bright yellow > green > dark blue green

by doing that you're applying color theory, just tell me if you want to know more about it

same with the tree trunk: slightly dark red > brown > dark yellowgreen

your shading technique will help blend these colors but i don't have much tips for you on that one since it's such a broad topic

anyway, i'm not a perfect artist but i will try and give an effort to make a fellow artist better :D
