(I) Any usage shall be fully defined in any final contract.

Where you want to use an image, will it be alone on the page, at what size, and how many shall be produced, before we need to renegotiate?

(II) When I will recieve any royalty checks owed to me, every month, quarterly, semi-annually, or whenever a dollar limit is hit?

I'm not a fan of the dollar limit scheme, unless the limit is low enough to ensure that I'd recieve every, or almost every cent to which I am entitled. I much prefer a monthly or quarterly exact sum payment structure.

(III) Any initial deposit monies, paid by any licensee shall be held as distinct and unrelated to any royalty payments based on sales.

If my art helps you sell your product, I want to be paid for it; so deposits are held as distinct and unrelated to royalty payments based on sales, unless we agree to a single payment buy-out.

(IV) The presence of a by-line, and control of its size and/or location.

The presence of a by-line is a very important fact of life for artists and illustrators, and I need to be able to have complete oversight of this crucial aspect.

(V) I need to see everything involved in a particular project.

What this means is, if you're going to be using my images for a book cover, I would seek to review the manuscript. I'm making new art everyday, and it is possible that I have an image which could be more appropriate for the text.

(VI) I reserve the right to examine any licensees sales books and/or reciepts for sales, of any product featuring any art which I have licensed.

I must insist on this clause, as I have heard/read many horror stories, about non and/or under-paying licensors of fine art. I don't expect this to be neccessary, but it could become so, so I would have it included in any contract within which I am to recieve a royalty payment.
