Rajan,
I've looked this set off and on for the past day or so,... and #2 is my favourite. Today I just "saw" a human figure ( looking left,... arms out stretched,... ) with the brown weed (brush) on the figures "chest". For me it adds a most surprising element to your image. Not sure if you planned the composition with that in mind,... but wow.
cheers, Leszek
