I got back three very different perspectives.
I got back dispute, question, criticism, suggestion, cross-reference, reinforcement and praise, in varying measure.
I got back the seeds of new thoughts.
I got back the makings of a stronger piece than I would have created alone.
I got to say that even though I know this can be a great way to work, and beneficial to all concerned, putting myself out there and dealing with what comes back can still be a challenge.
