You asked for an honest critique, so
I think you have a couple of issues.
First the lighting. The flash has been very harsh, resulting in red eye, and a large variation in the range and intensity of the light. Was it the built in flash? I would think about could you have taken the shot without flash? Or could you have used a more diffused flash source or even some off-camera lights.
Next viewing angle, could you be lower down at their level. You are looking down on them and that spoils the photo's.
Betty Boo, is just tacky and demeans the animals.
Next the bate is very obvious and it does not look at all natural. Look into hiding the food in something that may be in the natural environment.
You use the title Wild Dorset, but you have put in too many domestic links in your photo’s. It is obviously in a garden with food left out for them.
