mmmm not sure what you meant with the plant patches, could you send an image about it?
The greenhouse is a great prompt to have here, gonna add it to the list!
Hmm I tried finding some pictures, but really it's just about any mixed plant/flower patch, look around next time you're in a public park maybe? They're common where I live but I don't know how universal it is.
See how they're different lengths/shapes so it creates this particular, pleasant texture?? Even the ones where there's very few colors besides the green of the plant??? Maddening to transfer the feeling in pixel art, but so pretty... (don't worry about whether or not to draw it, at the very least you saw some nice plants :>)
