We use the Rook in all our images. We would like to use the same navy as the firm logo so that it is consistent with our other brands. It might be nice to have an 'R' in the center of the Rook somehow or make the letter R look like a rook.
If you use fonts that require a license, confirm with the client they're ok with it. For licensing reasons, it is better to provide your client with information on how to acquire the font rather than providing the actual files.
