Great work on the Mercure!
I don't check the request thread too often, I'm afraid. Hope you weren't halfway through already.
Here's a top tip that should be useful to everyone...
Before I even start gathering reference material for a new drawing (SB or FD) I Always use the search function of the site to see if it has been drawn, is on someone's worklist or is even mentioned or discussed. Always. Then you can be fairly certain you are not duplicating an existing drawing or pissing on someone's WiP.
