Hey,
This is my final render for the LuxRender secret spaces contest. I’d like to work on it more, but I’m not going to have much time to do so this month.
LuxRender 0.8, Blender 2.5, Blender 2.49b and ngPlant were used. 
this looks almost realistic! i thought this was an actual picture taken by a camera for a minute.
Looks great. I am playing Risen now and this reminds me of that game.
Looks good! Maybe a little bit more of a “clothy” type texture on the cloth would help the realism? Unless your going for a tarp effect.
You know the gimp has a great filter for generating cloth textures. Filters-Artistic-Clothify
nice plants…are they alpha mapped?
