As a reminder, the Literacy Consultancy are also running
this
competition for radio and theatre writers.
I don't know anything about TLC, especially how much of an achievement it is getting your work reviewed by them. I'm sure I've seen details of writers festivals where they have a stall and all attendees can have a free review session with them.
Nonetheless they look fairly kosher compared to many similar outfits, and seem to have genuine industry contacts, so probably worth pursuing.
