[edit] The side of the Maroon colored wall edge, you could clone out?

agreed...plus I would get rid of the glass on the left.

also her face is a bit too blur-softened for my taste. I would go for a more subtle and smaller scale softening rather then blurring the whole skin tones and masking out.

what would you say is the best way to retouch the skin? ive only been showed the blur / mask and then lower opacity way. Thanks for your help! x

I favor a more subtle and targeted approach.
for example if you need to get rid of/ soften some lines on the neck, dont blur the whole neck. heal, clone, or d&b each line separately and adjust.

I also prefer to separate details from tones using the techniques explained in the thread below:

and this lady who also is a member here has some nice tutorials:
