Critique my Photographs?

I use a Nikon D3100 -

Please be as harsh as possible, It doesn't really matter, I like strict critiques, they do help me! Thanks for your time!

Added (1). I do have more photos on my Computer but they're all over 15 MB which exceeds Flickr's Limit.

I love them!
you edit them really well, too…
the camera seems pretty good, but maybe try investing in a better lense in the future to make them pop even more.
(:
also try uploading some low light ones.

From the 3 I saw (which really isn't much to go by), they're so-so. You have a good sense of composition, now just working on lighting and exposure. The first one needs more contrast (and I don't mean just going into Piknik and adjusting). There's a LOT of gray. The sunset is really underexposed. And really, there's nothing that holds my interest as sunset pics are a dime a dozen without something to make it spectacular. The one with the deck chairs is ok. The sky is really blown out and the pole just chops the photo in half.

Keep practicing. Join groups and forums on Flickr while you're there (and not just the groups where people give out a bazillion awards without actually giving constructive criticism).

Not a lot to go on… Difficult to know if they are the exceptions or the norm…

they aren't very interesting…

the bridge would be better if you did a longer exposure to get a better sky and no people…

So boring, photograph is not just to take a camera and press the button!
