Hi Folks, I know this has been covered before, but not for illustration specifically. I've just finished this large illustrated map for a theme park, which was put together in Photoshop, hence many layers. Client is pleased with it, but has asked for the original layered file, I presume to tweak bits as he pleases. This is not something I've done before, and I'm not sure I like the idea of it, so should I refuse or just hand it over? They will need to come back to me anyway if they need to add any more rides, etc, as they were all hand-drawn. Anyone had this before? I should've said, my client is the design firm working for the theme park.
