Seems like your friend only gave you theme recommendations.
To me "hive themed" means green and black, but maybe you could ask him if he has anything more specific in mind. Generally when folks commission a build from me (or ask for build advice), I ask the same questions.
- What's you exact budget. How much are you willing to spend. "semi-budget" could mean so many different things for different people
- How often do you use a numpad? Arrow keys? Nav cluster? F row?
- What colors do you like?
- Do you prefer linear or tactile switches? Light spring or heavy spring?
- Do you want any special features? Rotary encoder, bluetooth, etc?
- How long are you willing to wait?
And a question for you as the builder: are you OK soldering? From your experience, it sounds like maybe you want something hot-swappable
Answer those questions and we can really help narrow down the built. Otherwise you're going to get a lot of "GMMK Pro, Boba U4Ts, GMK Terror Below" style answers
Keyboards can be pretty personal pieces of you battle/work station. Getting those little details right can change the typing experience from "this is a tool" to "this is _my_ tool"
