Ideas on how to handle sexy but not nude art? (Patreon)

Apparently I can be suspended from Patreon for having pictures with cleavage or butt cracks up for non-patrons.

That means most of my SFW art may be an issue as I post them for free and they have cleavage and butt cracks.

I'm not sure how to go about correcting this. I don't want everything behind a paywall, but I don't want to lose my Patreon, obviously.

A few ideas:

1. Maybe I can post previews and link to dropbox files for the full res. I would have to spend money to have the dropbox space, though. Not ideal.

2. I make all of my art patron only unless it literally has no sexy stuff, which won't be much. Even the Patreon reward pack images might be an issue with Midna's butt out and all. I'm not sure where the line is. :/

Any other suggestions?
