What do you think of this rep?

I used to do pull ups / chin ups on rings where I would touch my hands to my upper chest . . . However this led to a lot of rounding in my upper back and just not the nicest looking reps.

I now try and keep my shoulder blades well retracted at the top of the rep. This means that my hands don’t touch my chest but I feel that these are nicer reps . . .

Thoughts?
