every forest type has some numbers on the right hand corner if you select the trees for it. If you make them smaller, it will get denser (you can also change density while converting)
Not bad for first conversion, control placement could be improved a bit. You can check it in CFedit by pressing space and then checking each control site one by one in 3d.
Tried to use the little rock by 7 as an attackpoint and just couldnt find it!
