I have looked at your site and can see you have a photographic eye, one that can capture the difference from what you see and others percieve, that is a very good starting point. I do not critique fellow photographers work for the simple reason photography is an art in the eye of the individual and it would be wrong to put my view on others work. I give a for instance, put 100 photographers in a room with two pictures one awfull and one brilliant, the room would be divided 50/50 on each picture some would see quality in the first and some see the same with the second, but both would have faults picked out in them at the same level, I hope you understand what I am saying, we all have a view but we are all individuals with that view.
My one bit of advice to you is this, you are a young photographer making your way in the marketplace, I am now getting on a bit, in the past I made the common mistake to photograph everything, but I mastered nothing with the exception of my camera, I now specialise in certain image types, one month I could be photographing babies, the next lions, then I may spend six months doing buildings or landscapes. My point is specialise in a one area, take your market point and focus on that become a specialised artist, by doing this you will do two things people will know you as a photographer of repute in an area of the art, and secondly which is most important you will learn a lot quicker the art of photography, take one subject and continue to photograph it, with different lighting, with different angles, different camera settings, take 100 pictures of this all different but the same subject. Out of that 100 pictures you may be lucky enough to find 5 that really are brilliant, you have found the sweet spot, you could never do that if you take one or two pictures of a subject and then move on to another subject. By doing this you are honing your skills for the future and discovering what you as a photographer can actually do, and do well. I do hope this helps you on your road.
