Tree hunting

Today in class we started our new project that is focused on drawing. I am really excited for the project though because we are designing tree houses! There is nothing not fun about that and I am really stoked to start thinking of stuff. To be honest though, I am kind of nervous about the project because I will admit, I am one of those "anti-flow" people. I am going to really try to just let go of my drawing insecurities for this project and do my best.
These are some treehouses I saw online that I really like...
