I completely forgot about the method to draw petals / multiple leaves by drawing them inside a circle. I started using it from the third plant. For the unknown rose, I had some troubles figuring out how to construct the flower itself (since constructin every single petal from top to botto would be a total mess), then I decided to build the cylinder as usual, then drawing the outermost petals. After that I constructed the rest of the petals starting from a central axis and giving priority to those closer to the viewer and working toward the external border until the form is filled.

I also realized that I made some size errors, like the leaves in the last image that are way smaller than the reference, or the corn cobs that are positioned too far from each other.

I couldn't find the names of the last 2 plants, the photos were in the channel sticky.
