~ I think maybe the busy-ness of the background is making the main image less vivid. Maybe trying to define her against the background more would solve that. For example bluring some brushes in black or white and place them behind her and try different blending options and see if that changes anything.
As for the C4D render, I always use the same 2 or 3 from Archangel Designs.
Remember that website? I'd get a link but my PC crashes everytime I open Firefox as of 10 am this morning and I have it in my favourites.
Can't find it using google. T_T
