Stairway to heaven is pretty cool, i like the perspective of it. You might wanna think about cropping some off the top so you can't see it end, so it gives a more "infinite feel".

I also like Tag. If your ever over there again try getting a more straight on angle, and having a bit more light and i think it'd be pretty cool.

bench is pretty cool too, the depth of field works very well for it. it might be cool to have a shadowy figure sitting on the second bench, out of focus, If you ever re-shoot it.

Nice job, your getting better, you should try to go somewhere though, photograph the city or some people or something, i always find it hard to find interesting subjects around my neighborhood.
