For a beginner, I think you've done a pretty good job with decent photographs and you have controlled the Depth of Field pretty well.
However, I personally think the pictures seem a little "flat" and that's most likely down to lighting (for example, in the shot of the bridge, some sunlight breaking through the trees would have made the shot more dynamic).
On the individual pictures, I'd make the following comments (This is just personal preference though!)
First one - it's an interesting door, but I'd have cropped out most of it and focused more on the actual texture of the peeling paint with a close up
Second one - Nice control of Depth of Field, not so nice choice of flower: Much better to find one that isn't dying
Third One - this is my favourite but would have been even better with a bit of dew on the leaves (artificially sprayed on if necessary...) and possibly cropped tighter onto fewer leaves
Fourth one: As I said above, the lighting leaves this a little flat, but you've done well to get the whole bridge in focus. Nice control of Depth of Field
Fifth one: Personally, I'd crop it so the horse is the major element in the photo rather than the background. Also would probably have tried a shallower depth of field to blur out the slightly messy trees in the background
Sixth one: nice focus on the main subject, but horrible choice of brick wall background
Seventh one: Nice focus and decent lighting, but not the best choice of subject IMHO.
As I said at the start, they're impressive photos for a beginner and a bit more attention to detail will really let the photos shine.
Good luck, and enjoy your photography
