Hello.

Your arrows seem very well made and it's clear where one edge is in relation to another.

In the "drawings as exercises" portion of lesson three it says that less than half of your submissions should be from the demos but you've used more than half, as such it's difficult for me to properly critique you. If you have difficulty finding reference here are some links that people have posted in the discord.

alternatively you can just google image search or look at real plants.

But from the plants I don't think are from any demos it looks promising with clear shapes and lineweight to seperate them.

Hope this helps and good luck.
