Jake I am not an expert, so this is an 'any response'.  Personally, I would be interested in discovering all the facets of your multiple talents.

There was a discussion about it (not here) a few months ago, and the consensus was that for professional photographers it was better to separate the different activities.  The main reason was that the clients would not understand why the stock photos are so cheap compared to the amount they personally charge for other projects, which could be a source for potential bargaining problems.  You also have to consider if your clients would benefit from such diverse presentation.

But if your other activities are hobbies too, then it's a different bargain, and incorporating the multiple activities could be very enriching for everyone involved.
