If I may humbly offer a couple of suggestions:
(i) In your pbase web gallery change the style sheet to one where it easy easier to scan the thumbnails. The current style sheet that you are using looks fancy, however, it is very difficult to get a true feel for your images.
(ii) Go through each of your galleries and pick out the best 8-12 pictures. Throw away those pictures you haven't chosen - though think carefully what it is that you like about the ones you have kept and those you have thrown away. If necessary throw away all the pictures in all galleries and just keep your best 12 or so. By keeping the number of pictures small you can keep the average quality high. Over a period of time you will be able to grow the number of pictures you keep by understanding what it is that helped you take the better pictures.
(iii) Keep it simple and keep it clear. You need to work harder on your composition to (a) make it much clearer to the viewer what the focus of the pictue is and ( eliminate distractions that weaken the overall composition. Too many of your images are of the 'broad view of a scene' type with no clear visual elements to lead the viewer into the image, hold their attention and engage the viewer emotionally.
(iv) Think different. I can best explain this with an example. At the weekend I went with some friend to visit a Chateau close to Paris. The natural reaction is to take a view of the front, the courtyard, the buildings. However, I felt that this would lead to the typical 'happy snappy' tourist type of shots with little to differentiate it from any other tourist who would take a picture. Instead I decided to work on a compositional theme that I am developing with an object in the nearground set in the context of an out of focus background. Whilst this picture isn't necessarily going to win awards it has more impact than a straight shot of the chateau. I have focused on the ball (using the 1/3 rule to position it in the frame) then balanced it up with the out of focus person to the right. It is by not taking the expected shot and focusing on some compositional theme that you will develop your photographic skills.
Your off to a good start, I would suggest to keep looking at other peoples images and seeing what works (how they use distance to subject, lighting, point of view, perspective, depth of field) and try and build it into your own work. Get a good book on composition and follow closely what they have to say. And finally keep taking pictures.
