Hi Euro!
Welcome to
RP!
Great shots!!! But, not having seen the originals, is difficult to say what else, if anything at all, could be done ....
For the catchlights, I use this very simple method:
* Create a new blank/empty Layer on top of the others ...
* With a very soft/fuzzy white Brush (Opacity set to 20-30%) simply paint the catchlights on it.
If the result is too strong, simply blur your catchlights Layer and/or lower its opacity ...
