Excellent work on the model & texturing - textures are fantastic, and certainly make it look anything but a "simple model". It's very realistic, reminds me of my old school building! Looks like a good candidate for the marketplace to me - I'd definitely buy it. When I use a lot of trees in the distance or middle distance I tend to render them separately and put them in as 2D objects - they usually look just as good, and it saves space & helps to stop Bryce getting its knickers in a twist. Also I never save to the same file twice when working with trees, I do a "save as" every time, and just clean up occasionally when the trail of files gets too big!
