I do like how Draco and Harry are getting along.  I do noticed that Professor Snape feelings towards the boys has changed too.  It's interesting that Draco can find Severus and Harry due to his magic.  I wonder will this magic help later in the story.  Don't get Harry angry or he'll let his magic express his feelings.  I feel for Severus who didn't think he would feel different for Harry.  I never liked Dumbledore with all his secrets.
