First things first Holly...you need to make certain you have the $$ to "support" the site as you say, and THEN you can introduce your preference for artsy/glamour porn into the mix...but I think you will agree, common sense dictates you first hit upon the minimum needed to ensure the site's existence, otherwise it is all BUNK/MOOT/dead wood (or No wood lol)
So might I suggest, taking something like that LAST picture you posted above as a reference/starting point....it is a very strokeable, EXPLICIT-type shot that your garden variety pervert will want to jerk to, and I mean the typical jerker-offer who is willing to part with the requisite $20-30 monthly fee. Get this type of content and shit online FIRST, and then start mixing in the cool, different shots like the one's with the graffiti and interesting scenery.
Here's a suggestion: Take a chick like this one above, and shoot a blow bang in and around this abandoned graffiti-stained Dairy Farm...have her blowing 6 or 7 dudes, in various combo's and poses and settings around the place...culminate with her gobbling the splooge in the area where they used to milk the cows. THEN go back and shoot the artsy shots like you have, and MIX them in on your site for the paying jerker-offers to see and appreciate while they are messing themselves to the shots of her swallowing goo. You need to introduce the paying perverts GRADUALLY to your cool, thoughtful stuff....kinda like a reverse weening process. Me personally, I have always wanted to see your beautiful unique style mixed with a Down-the-Hatch type video anyway. Maybe then I'll join your site

Here's another free Burg marketing tip: YOU, Holly (porn's version of Underdog's sweetheart, P. Polly Purebred) are a HUGE marketing tool in and of yourself. You need, SOMEHOW, to emphasize, remind and otherwise bring to the FORE the fact that YOU, gorgeous/sweet/charming Holly, are the one coming up with and SHOOTING this filth! I am totally serious....it is one thing to see porn today with semi-hot chicks getting banged in all positions and then swallowing load after load....it is another thing ENTIRELY, to meditate and ponder and whack off to Porn that we realize is being orchestrated by YOU...when i see such filthy spectacles, and then further realize that it is YOU behind the camera, and that YOU are actually there shooting the shit....well, that amps up the hottness factor considerably, and therefore, gives YOU and your site and your content an invaluable EDGE. There should be a shot of a shot where YOU, Holly, are visible photographing the action up close...picture a chick on her knees with 3 dudes blasting away into her mouth, and there is P. Polly Purebred (aka HOlly Randall) right behind the girl with her camera, shooting away (with a smile for effect, and maybe even your jeans unbuttoned (nothing showing of course) to "imply" you were diddling yourself to the action at somepoint....ANYTHING to ensure success and give you that EDGE I am talking about.) it is almost as if YOU, Holly, become a vicarious, non performing, NON-porn star PORN star....
Like your signature says Holly...HAVE a few pictures on your website for each shoot of YOU respectfully lubing up the girl's pussy. I AM TOTALLY SERIOUS! That alone will bring in a certain core of membership and viewers each month...EVEN Jeff Steward would be interested in seeing You, Holly/Polly lubing up a chick's pussy.... You may recall Holly, it was I who suggetsed you use that line as your signature a long time ago...

Do you follow all of what I am trying to say here??? Gosh, so many people and companies would pay me oodles for advice of this nature and thought ...

THIS will then allow you to get all your serious, thoughtful, impressive "art" into the mix.....
I KNOW the jerker-offers here at XPT, guys like Bornyo and Zen and Willie, et al, would definitely agree that seeing PORN where YOU , Holly/Polly are actively involved in as a producer AND where you are actually Seen to various degrees in certain parts of the action, is definitely a marketable entity above and beyond the norm.
Dont say I never gave you any decent, thoughtful advice, "Polly".
luv, Da Underdog/UnderBurglar
