Looking for some construtive criticism on my first shots

[Mister Hahn]

Hey guys my names Chris, I'm 16 and I just received my first SLR Camera today. (I went with the Canon Rebel XT) Thought I'd benefit from some criticism on my first shots. Sorry if they might be a bit blurry, I have to work on that...

They're not bad, but they all seem to be lacking a real subject.
