I absolutely love your work and would love to commission some trees and bushes specifically for my game if you are open to it! I am a pixel artist as well but I can't draw a tree for the life of me lol
I also wanted to let you know that I was browsing artists on Fiverr for my foliage needs and I saw someone sold this tileset.
If this wasn't you, I would definitely report them to Fiverr and I will report them as well so that we can hopefully get this gig taken down.
