Help me improve please? Examples.

Those are not half bad. You have a good balance between subject and background, your composition is generally fine (you seem to have an understanding of the rule of thirds, which is a useful starting point for positioning your point of interest) and you have chosen an interesting background, a lot of texture and a good colour and tone to contrast with the doll. You have also shot in diffused, overcast light (when do ever get anything but in this country?). Always avoid bright, direct sunlight (yeah, right) as it produces harsh shadows which really do a doll no favours.

Pointers. Now, there might be a reason to move to a DSLR as one of things I would suggest is that your subject is slightly over exposed. Not so much that you are getting too many bleached out areas (those highlights where all there is is a big oatch of highlight, with no detail. It has all been blown out). There are some on the top of the head, but you are still getting some midtones in there, so not a distaster. However, by lowering the exposure, you would get more midtones throughout the doll, which would add interest and the additional shading it would add would help moulding shadows to the face, gving it more of an impression of three-dimensionality. At the moment, it all looks rather flat. Now, what is happening is that you have a light subject against a darkish background. The camera is metering all that and giving an exposure that averages it out. So, the background is slightly darker than it would be if it were photographed alone and the doll slightly lighter. With a DLSR, you would be able to "compensate down", which means reduce the shutter speed from what that average metering thinks it should be, to effectively give the right exposure for the doll alone. The background would also be darkened, but I don't think that would be a great loss. I have no idea about point and shoots, but I understand that some also have the option to compensate down. If yours does, and you are doing this light-against-dark thing again, try stopping down by at least one stop. Check your image, and increase or decrease until you are getting some nice shading on the face.

Another possible thing to think about is position with respect to the subject. In portrait photography, which these are examples of, the most compelling pictures tend to be taken from a point at the eye level of the subject. Some of these are slightly high, which is understandable as you have a very small person to photograph. Try getting right down and make sure you are shooting level with your doll's eyes. Not just so that you can see them, but so that the camera is actually at the level of the eyes. It also adds realism as high shots tend to emphasise the fact that this is a small doll, rather than a real person.

The unedited pictures also have a slight blue cast, which is the result of the overcast sky. This doesn't look so marked in your edited versions, so you might have noticed that yourself. If you have the option to adjust the white balance on your camera, that can save some work in Photoshop.

ETA: Another thought. The subject's eyes are usually the most compelling part of a photo. They don't need to be directed towards the lens, but it can help add interest if they are clearly visible. Now, because of your high camera position, the shape of yoyr doll's eyes and the shadow the lids are casting, they have disappeared into the gloom. I see that you notced this when editing and presumably dodged (and coloured?) them. another thing to try is to bounce light up into the eyes at the time of taking the photo. Hold a sheet of white paper, angled under the doll's chin, and just out of shot. Alter the angle and position until you can see that you are reflecting a bit of the lovely English sunlight (o.O) up into the eyes. It will also help lighten any dark shadows, not that you have them here.

But, overall, these are nice portraits. Keep going.

 

Do you use a tripod? I think that would help.

Also taking the picture from further away may give the resin a more glowing feeling.
