I know you are following a set theme with this set, but I personally would feel it'd benefit you more if you brought something "new" and "exciting" with each iteration.
You are a creative guy, and although Terra is nice, I personally feel that I would be more excited and look forward to each new element if it was something more than just a palette swap.
Similar to hisuis design, it feels like you have found a formula that you both like and stick to it, but this can quickly get repetitive (at least to me personally).
You are one of my favorite designers, hope we can see some innovation and breaths of fresh, creative air moving forwards. 
Aren't most GMK sets the same exact product with different colors + or - a few keys?
Like anyone that collects artisians of the same sculpt in a new color way, it's cool that they are the same with different colors, making it a set. That's the point.
Hmm, I think you missed my point completely.
To put in to simple terms, you know how there are countless of dolch colorways, countless of hyperfuses? Just by looking at them, you can tell what it is. This is on another level, though. Looking at Rens and hisuis sets, I can tell it is theirs by the style - which on one hand is good, to have such a distinct and recognizible style. I however kind of feel like GMK as a whole is stagnating a bit, and I am getting bored.
I look to talented designers, like Ren for example, to wow me and present me something new and exciting, as I am losing interest looking at what we have circulating now.
Handarbeit is a bit of fresh air, unironically, I hope we see some norms being broken moving forwards.
Maybe it's not going to happen in this series of keysets, but all I can do is share my personal feedback, regardless if anyone agrees or not.
