I really like this one! Been looking for the SA set for a while but it looks like this color scheme and novelties look great on GMK also!
My only concern is that the muted green ends up being more saturated than in those nice renders. This has happened before e.g. gmk plum and gmk nautilus. I would be all over this set if it would be 100% certain that end product would look exactly like those renders.
Have you tried looking at these through an IPS display* :O. I thought Plum came out perfectly. There's only a handful of photos that perfectly capture the colors. It's probably the most difficult set to photograph (tbf almost all keysets that have non-muted colors are hard to photograph, haha).
Nautilus concerns me though cos the yellow from the renders is brighter than the yellow in Zambumon's pictures. But eh, it could just be the filters he added to his instagram photos.
*It won't be 100% faithful to whatever was rendered but it'll be close enough.
**I didn't buy either of the GMK sets you mentioned and I am very, very sad
Edit: The SA Camping photos here have greens that are more saturated than the renders. I get what you mean
. It suddenly looks a bit tacky if the greens aren't muted
