You have less problems than you think, but you don't want to run into a problem at the wrong time. You need to practice in the treestand (though not necessarily from a great height) just to become familiar with all the awkward angles and have a good INSTINCTIVE understanding of when your limbs might have a chance to smack something. Practice close shots shooting very canted even fully horizontal or more. You may not shoot your best that way but you can shoot plenty well enough. The longbow shot instinctively is very versatile and can work for nearly anything with practice. Besides the bow, you have to have an instinctive feel for your tree, the branches, the platform, and all of your surroundings.
