I think it's a big improvement.
Working hard to bring procedurally generated compound leaf types. After that... occlusion shading. If you're wondering, the interface is MFC +C+. All common controls are sub classed for custom colors and bitmaps. The property grid (right) is a custom control, made by me. The color picker uses the XColorSpectrum control by Hans Dietrich. Thanks Hans.
Will post again when I have some shots of the new compound leaf nodes. The images above still use the single leaf type geometry.
