awesome quality. the lighting and the colors have this slightly pale and grainy look which resemble photos quite more than what you see usually in 3d scenes, so it gives it quite a realistic feel
as you produce your own textures you could sell those and include a quick guide to the parameters you use in SpeedTree. This way you could sell it legally and buyers (requiring SpeedTree) would be able to re-create everything.
If you have other reasons to not sell your assets I can understand. but if it’s only the SpeedTree asset license limitations, with the above method you’d certainly get quite some buyers (myself included)
looking forward to that!
