Congratulations Brendan!!!
Took some more epiphyllum (cactus flower) images, and after inverting and adjusting hue and color balance, it started to remind me a little bit of an underwater scene. The stamen seemed almost as if it could be coral, so I tried to bring that out, as well as an overall aqua marine feel. Experimented with different Nik Color EFEX pro filters. Don't remember every one I used, but the main ones I think were, Photo Stylizer, Color Stylizer, Darken / Lighten Center and Tonal Contrast. Also used some Topaz Detail, lots of touching up and experimenting with selective color adjustments.
