The new trees look great. Unfortunately you can clamber onto any solid branches (a lot are even accessible from the ground). Getting to the top of the larger trees isn't too much trouble once you're on the first branch. Worth keeping in mind when making new maps - don't want people making jumps to parts of your map you didn't intend people to be!

Some of the branches are fairly low and you end up making it impossible to jump at all underneath the trees. If you use individual blockers on each branch, or even just a couple, you chew through the budget very quickly. 30 trees can cost more than 10% of the total budget if you use two or more blockers with each tree.
