(IGNORE THE BLUE MOON LOGO TEXT THING...)
While nowhere near perfect, I decided to utilize a few things to keep the font from being too distracting. The first thing was that I did my best to allow it to flow with the render, rather than fight it. It moves outwards from the woman, and rides along with the motion of her hand, and her body language. I also decided to make it the same color as her body, so that it seemed to be an extension of her: it would not pop as much.
This one isn't good. Honestly, it turned into an experiment to manipulate some fire onto the guy's head. The text just goes out across the piece, with no real regard for anything, but being a phrase to be read. It's just horizontal, boring text. On it's own, against the background, it might be "okay" at best, but it just clashes horribly with the render.
This one has decent placement, but is still distracting. It's bold, in your face, and takes your eyes away from the eyes. It's also a little hard to read.
I was most successful with these two, although by no means perfect or ideal. The text is subtle, blends in with the piece well, and is still readable. You want to aspire to get that "kind" of effect.
