So, long term lurker here. Finished my sci fi WIP and sent it to about 6 agents. I’m UK based and the pool of them here isn’t huge. I’ve had a couple of rejections but amazingly got a request for a full MS. That then came with the nicest rejection. A summary of structure changes, what didn’t work and a couple of writing tics that I need to straighten out. So all encouraging. I think the suggestions are all valid. So I’ll do them and resubmit to the agent because he asked me too. Do I withdraw my submissions from the other agents advising them I’ve had positive agent feedback and then submit again when I’ve fixed it up?
