Old pic, edited for first time

Didn't get out and about to take any photos today, so dug into my files and pulled out this one taken in November last year. I'm trying to improve my (dubious ) editing skills, so thought I'd have a wee practice.

I'm trying out Rawtherapee (this is the first time I've used it) and it's OK, but like all software, has its learning curve. Reasonably happy with my first attempt at using it.
