END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

Nice find!

Image editing will always give you the most out of enhancing any fractal - but many fractal artists frown upon the practice  (I swear by it for finalizing a piece of Art - which is distinctly different from a piece of Fractal Art)  (Just plain "Art" is much more open to any image tweaking, editing, or altering you want, but many people feel Fractal Art should have only minimal post work - if any).

That said, have you tried different light sets? 

Are you using point lights?  They can help highlight specific features of any fractal in M3D, and I think hard shadows can be calculated for each point light individually for better effect.

Good luck refining it and do post your results
