Criticise my photos please?

I have a Nikon d3000 and am starting out in photography. My friends look at my pictures but they never tell you the bad things.
I have taken my best (that I think) photos
if you could give me your honest opinion I would really appreciate that.
Thanks
Added (1). Ohh my forgot the link: P here it is

We need a link please! You forgot the link to the photos!

It sucks… Oh wait i haven't even seen it yet. Yeah, we need a link to your photo's.

The rose but thing is pretty nice. Overall I don't see anything interesting. The playground and the rocks might have looked cool to you but why should it be interesting to some random person? That's what you have to ask yourself. Does a burnt up corpse say something about the war that we don't hear about on the news that we need to? Does that angle of Big Ben ___? Even if this were just about your family and vacation, the odd angles, cut off heads, close ups and long shots leave me to ask if I have sen anything that will make me remember your holiday. You're just not getting across what you want to.
The overtly strong editing is problematic.

You need to think more before you shoot. The last part of the photographic process is pressing the shutter button, that finalises everything, it's like the signing of the contract.
So you need to work everything out before hand. Stuff like the exposure, the composition, the point of view, the content. Don't be content with just recording what you see, try to see things beyond it's face value.

Number one is nice might look better in B&W also making the contrast stonger, love number it is nicely cropped, number 4 also one of my favourites i think you could try cropping this even further though like getting right close to where the water droplets are, love how you framed number 9 the rest are ok but the ones i mentioned stand out to me

I think you need to work on the overall composition of the frames. Watch out for strong horizontals which cut your pictures in half.watch where your horizon line lies because that alters the whole feel of the picture. Before you take a shot, ask yourself why you what to take the picture and why you want to capture that frame. Use the space in the picture to emphasize what you are trying to get across to the viewer. I think you also need a theme because from what I see now, you just took pictures for the sake of taking pictures. Often you have to take multiple shots of a place on different angle and one of them will be magical. I agree with the comment that says you shouldn't edit the pictures so much. If you take an amazing picture, it won't need photo shop. Keep taking pictures of everything and anything because that's how you will find your voice. You are off to a great start, just keep going.
