I would really appreciate to learn from your code, this one is really excellent.
May be you consider your moss object itself as "not particularly clever". You
are wrong with that. But as with your train, your guitar, or the stones from
your (natural history) museum your textures are really wonderful. I would really
like to learn how you did the stones or the moss here.

I personally think that your use of focal blur here is completely correct and
not over the top. In some areas of the picture it looks like a little bit to
much, but this seems to be more due to the geometry of the scene which looks a
little bit like the edge of the step of a staircase. In this case you must have
smaller areas of sharpness and decreasing sharpness down the stairs which seems
to be the case here. So I interpret the settings as correct.

Best regards,
Michael
