I'm a beginner with pixel art and have been working on this little cactus plant for fun. I'm not planning on integrating this into anything bigger but I would really love some feedback. I've looked at some pixel art videos on youtube and at some games (mainly backgrounds) but this is the first thing I've done by myself.

I got colors from another image of a cactus but I drew the plant from my imagination. I've seen some beginner tutorials where they do a silhouette first but I drew this piece by piece, pot first and then did one circle (?? the little leafy guys) at a time. I would really appreciate any feedback or links to helpful tutorials, I plan on improving it! (I read the pin but if I posted the image wrong I'm sorry)
