Hi Nina, welcome to the board.
First of all, that?s a nice shot, we?ll done.
I see that you already improved the image pretty well, but you asked for some suggestions so I have a few.
A ? focal point
To increase the focal point in the image you can consider to add depth of field by blurring the background. A good tool for this if you have CS2 or higher would be the
Lens Blur tool. The Lens Blur tool also has a pull down menu box in which you can select the channel that you want to use for your lens blur. Now if you would add a black and white gradient of the size shown in red (A), then Lens Blur is going to create a smooth blur based on that gradient. Of course you have to avoid blurring the swans, only blur the water.
Now I can?t be too specific as how this all works (would make my post too long), so feel free to check out Russell Brown?s excellent Lens Blur tutorial called
Hocus Pocus Focus on this page:

B-C-D Sharpening
I see that you?ve sharpened the image, but you went too far in some areas. A good indicator of over-sharpening are halos that will appear at edges. Took a look at the neck of the swan (B) and look at the magnification; notice how the edges are pretty bright. This is a sign that you?ve gone too far. Now mind you, halos can?t always be avoided, but you have to keep them under control.
I already noticed halo like edges in the original photograph, so I wonder if the camera already added some slight sharpening on its own, which can in some circumstances only make things worse. Btw, halos are not just white, they can also be black.
Photo retouching is always about taking time to analyze and? taking time to execute the proper corrections. In the case of sharpening too many people tend to sharpen the complete image, which is often wrong and can make things worse. Too much sharpening could increase halos but also make noise more visible. It can also bring out other unwanted details, like in this example in the water in front of the swans (compare before and after).
My advice would be for this image to duplicate the image, sharpen it, adding a mask, inverting the mask (Ctrl+I) and then paint with white on the mask with a small soft brush where you want the sharpening to be revealed (edges of swans, feathers, head, etc).
Change the opacity of the brush to have more control over the amount of sharpening.
You can even consider to use more sharpening in the feathers on the swan?s back (D), but again... avoid too strong halos around edges.
Personally I always prefer to use a product called
Focal Blade, which is a lot more powerful than any available sharpening solution in any version of Photoshop. It's also very good at controlling our enemy #1, which is halos.

I think the colors look fine althought here might be small tendancy towards green in the upper section, but it's hardly notoceable. Important when you adjust the brightness of the image (often with levels or curves) is that you keep the details in shadows and highlight intact, which you have done well, so that?s a good thing.
E ? cloning
I would clone out area E, it?s slightly distracting.
From a photographer?s perspective I would also avoid to put the subject ?in a box?, which happens when the edges are too close to the main subject. For example in this image I would have preferred more space at the top and in front of the swans, it gives them ?virual? breathing space, it makes the image more powerful.
Just always remember; don?t always remove noise of the complete image, sharpen or color correct the complete image; photo retouching is not just a matter of WHAT to do, but also about what NOT to do, so use masks if they can help you to get better results and forget about the fact that it?s more time consuming if you want optimum results.
