softwares: Blender 2.70 - Onyx plant (textures: from www.cgtextures.com)
It took about 7-8 hours.
Nice use of colours on the mat to mirror the plant. The green leaves stand our really well against the otherwise very warm tones elsewhere. I would have been tempted to have a little splash of a different colour on the butterfly - perhaps something a little turquoise? The plant looks a little cramped, being cut off at the side and top.
Beautiful and artistic.
