like i managed to power through 
your instructions are amazing and i learnt so muchhhhhhhhhhhh but i struggled with many things 
1- idk where i msessed up but foliage grows below the flat object
like the angle is correct but idk where i messed up
I had to make a cube below my land just to hide it
2- my stems kept getting ... extra wiggly idk why like i struggled so much with their placement .. my result is above

3- you did amazing job instructing us but i will be hoenst... this was not for beginners :( i struggled alot with the math... i had to return to math schoolbooks to see what were you doing.

overall .. thank you. it took me 2 weeks
