I found it interesting to start employing things I've learnt and draw from pictures like this. I've included pictures that I found off of Google image search and lined them up a bit to make any critique a bit easier.

I found the leaf construction interesting, though I have a dislike for spiney things and spiders and such so I kind of rushed the leaves, I might enjoy them better with like painting and such later on.

Was interesting to do most of this after having my wisdom teeth removed (they burred a hole into my jaw too). I was pretty nauseous, sore and shaky and fell asleep a few times so I probably didn't do my best. But I was really interested by the construction of plants themselves so that kept me from losing determination to continue. I think the fungi and sort of alien-looking plants were most interesting, they have very unique shapes and their essence sticks with me, so I might look into drawing them some more.

For the organic arrows, I dared myself to try doing a swirl, because I figured if I can error a oval into a swirl, I can do a swirl. After committing to that, I found following the second line I had to stop the line and continue or it'd break the drawing so it kind of stops and starts. I feel like it worked though, would be nice to know if there's a better way of doing such things, though.

Also when a tree is leaning it feels like it's falling over when I draw it but not in the photo? I figure that's because we imagine there to be roots underneath with a photo, adding a bowing line under that seemed to fix that illusion however. Not sure on any other way to fix this but its probably to do with symmetry, may be shadow would help.
