Wow, many thanks for the encouragement and advice, the time and effort is really appreciated.
Peggysue, please do feel free to make any changes to the photo you feel would improve the composition, I would really like to see how someone with much more experience is able to solve the problems that have stumped me.
Jimgarvie, I will work on my PS skills, particularly the cloning, I guess it will be plenty of trial and error!
Glamson, many thanks for the tips, I will try this “studio” setup again and put your advice into action. The changes you have made have improved the image substantially, it is great to see so much more detail brought out of the areas previously in shadow. Can I ask you what you did here? It seems to be mainly just the one area that has been affected by the changes, did you use the dodge tool here, or did you create a selection and apply changes to the selection as a whole (I’m sorry if these are very basic questions I should know the answers to before posting images here!)
Many thanks once again.
