In all I think this sounds like a good idea. Perhaps I'm a little drossy but I've sometimes found the Picture Gallery a little stuffy. There are also often children visiting with grown-ups; the kids quite evidently being disengaged. It'd be great if the kids' gallery were to showcase exhibits from children too, which I imagine it would - the Southwark pdf mentions visiting children up to 8 years but I really think up to 14 years would be better as there's so little provision for the 10-14 year group in the borough IMO - am I wrong?
