Strong Criticism Allowed

Hi guys, this is my first post and I'd like to say I love your forum, exactly what I've been looking for. I bought my self a 400d twin lens kit recently and I'm keen to learn the art properly, with some help from you all hopefully.
I've got a couple of photos here I took which I'd like some input on. Please be harsh as I think the best way to learn is through some good constructive criticism. I've only got the kit lenses at the moment but I'll be updating them as soon as the budget allows.
this is straight out of the camera
Just added a bit of a highlight to it
Cropped it a bit and played with the colouring a little
Straight from the camera, untouched.
Hope it's not too many at once, thanks guys.
