Hi Cathy,
I think its great that now that you have time youre learning more about how to use your camera and how to post process. Retirement is supposed to be about getting to do the things you want to do so its sounds like youre living the dream
If you like landscapes and are just getting into taking them
and live in Scotland, you have many hours of happiness ahead of you! Scotland is the best country Ive ever been to for landscapes. If you end up enjoying taking landscapes, before we know it youll be a master of tripods and filters as well as your camera and processing!
When I was looking at your final image above, apart from the awesome job you did at removing the hair, I noticed a couple small things I thought I could mention. Obviously just my opinions so feel free to ignore!
1) It looks to me like the focus point was on the hair on her shoulder so its just a little sharper than the eyes your sharpening and contrast shift has helped this, but because (it looks like) theyre global adjustments, the hair is still looking shaper than the eyes to me. If I were editing it, instead of sharpening the whole photo Id concentrate only on the facial features (duplicate layer, sharpen, then mask to only apply to facial features or duplicate layer and use the sharpen tool on about 15% and carefully apply). Similarly, you could also make an adjustment layer to bring out contrast (contrast, levels, or curves), mask it and zoom right in to only apply it right around the rim of the eye and the iris. By sharpening the facial features and not the rest, youd balance out the sharpness between the face and hair taking away from the fact that the face was slightly soft.
2) A small thing and totally subjective (like everything, lol): to me the background fights a bit with your subject because its quite vibrant. To help keep the attention on Anna, you could use a levels adjustment layer to darken the exposure of the background just a little.
3) And last, another small mention, her eyes are gorgeous (!) and although the increase in sat makes them pop, I think its a little too much here. It feels to me that between the second-to-last and the last image the irises lost a little depth. Id be tempted go to around 50% opacity on what youve done. (As a small aside: I find it can be difficult to tell if you have the amounts right while youre editing the longer a session, the more you somehow get desensitised and that makes it easy to become more heavy-handed. So, when Im finished editing, I find it useful to get away from the computer and come back for a final pass once my head has cleared (and my eyes have rested

)
Hopefully this hasnt been too boring and maybe helps a little, if not with this image than just with stuff to think about. Like I said, its all subjective and the points I mention are really just fine-tuning youve already done a fabulous job
