Really pretty, i can see the heart in there! :) The grey background gives a dusty feel and the different shades of red give depth. A delicate and beautiful piece.
The gray should've been left out, it ruined the pic :( The fractal is great but rendering it on a higher quality (2000-4000 on apophysis) would've made this frac *holds arms out a metre wide* that much better :D And just a tip, change the gamma to around 2-3
