William,

As long as you include Lagerpeton and Dromomeron, and especially pterosaurs, as dino-sisters, you're going to have trouble with the origin of dinos. Take a longer look, start with Prolacerta and Protorosaurus then throw everything that succeeded it in the Triassic into the tree. Maybe use Hylonomus and Captorhinus as outgroups if you insist on using pterosaurs.
