I would use thinners to trim that longer wispy hair that goes down to the breastbone (you want it quite short down to the breastbone ideally) & would have a go at hand stripping (finger and thumb) the excess hair at the top of the legs there - it looks like it would come out quite easily if you just take it slowly, a bit at a time. From the photo, his stifle feathering looks ok -I would perhaps take it in a little shorter towards his foot, just to show off the angulation a little better (not too much though, maybe half an inch to start with). It is much easier if someone can show you in person - whereabouts are you based, maybe there is someone not to far away who could help?
