I'm hoping I can get some help with doing trees. I've been unable to find any good tutorials so i've been studying other work to see how it's done, however it never turned out right so after messing around some more, I came up with this (and yes it was mirrored to make the other side):



Now this tree is going to be used with other buildings like so (isometric):



I think I got the trunk alright, but leaves i've never been good with. Any help will be greatly appreciated.
