hi, I have much to learn in post-processing (obviously?). Any advice on the here enclosed picture? (there is the initial version: too dark and not processed) and some attempts I've made on it with Lightroom 5.7.1. and Nik collection. Any advice? (One of the thing: there's this kind of halo in front of the horse (towards the left a bit maybe). I don't know how to (really) get rid of it) But that's not just the halo. I welcome other advices, too . Thank you!
