You’re dead right about the noise in #2 – I looked at it and it was taken at ISO400, so not normally too noisy, so it must be down to the contrast applied in processing. I’ll have a go at this again.
With #3 I was thinking the same, but left it in to add to the layering effect and extra depth to the shot.
#4 is very nice indeed and once again, great title.
I like the sense of movement in #1 which looks like some sort of Hummingbird Moth (pure guess)………../Mikka
#1 is a Hummingbird hawk moth. I’ve no idea on the plant type in #2, but I love it’s explosive appearance. #3 is a lovely scene & the title of #4 is great. Well done. A great set
