Lovely painting Roberto. I agree with both Edo and LM. Water/pigment control is the key to watercolour painting. I’ve been messing about for 5-years now and feel I’m starting to get the hang of it. Maybe I’m slow, but it takes time and as they say “miles on the brush”. Olly has some great videos on YT explaining this very thing. Worth your time to review and practice as he suggests.

Great job.
