Cypress Trees!

I've been wanting to add some more biomes to Project Hedra so here is my attempt at it.
The cypress biome was previously added but I removed due to some graphical bugs but I think it's time to bring it back! Anyway I could use a lot from your feedback
Here are some screenshots

The placement of the trees is in fact really simple for every checked there are 2 rules that need to be met.

• There must not be a tree 20 units apart
• There is in 33% chance this rule is randomly met.

  Remember to leave any suggestion or idea you have!
