Rock size aside the difference with and without the Microsword was barely noticeable, I liked it but it's fine either way, the overexposure on the second shot makes a bigger difference to the feel of the scape than the plant imo.
I found the same. I don't really notice the loss of the microsword, but noticed the missing Riccia in the front a lot more. But then that could be my personal bias against Riccia. :p
