Hi Arthur and Ian ...
Arthurs RP is definitely better than the OP . Wonder what Ian has done to it ....well he will know , hopefully .
Looking at your RP ... I am wondering where the blue thin halo is coming from .... outlining the left side of the birds ??
For me personally the sky color is on the " wrong side " of the blue spectrum and the birds are too bright in the lighter tones with loss of potential details ....- if there is any in the original capture ??!!
But this is just my personal view .. you might not agree

.... see my RP made of yours Arthur .
Cheers Andreas
