Thanks everyone, looks like it was a mistake to mention my age, I wasn't looking for sympathy, rather I just wanted to provide a little background, I think I worded it a bit wrong.
Regarding my LRPS, I have already got it, for an L the judges like to see a bit of variation, so my selection went down quite well. For an ARPS, the images have to be very coherent however.
All images which include mountains were taken in the lake district, when I was there camping for a week in August. Everything else is from the south east (Cambridgeshire), an area which provides a surprising number of landscape opportunities.
My monitor is calibrated, although I am very slightly colour blind, so that could explain some of the casts.
