I like fairly minimalist designs I think, happy for there to be some vibrant colour in there, but not overpowering. Clean, modern. Maybe ope to something that suggests that the individual elements of wellbeing make up more than the sum of its parts. 
A lot of great designs coming through that are clean and simple. I like to have the option of both a black and white background. 
Also open to more designs with some subtle detail now, as there are a lot of variations of a simple theme.

Potentially looking to incorporate 5 themes, so a 5 colour scheme potentially to represent this might be useful. 
 thanks 

Really helpful,  really responsive. Very happy with the finished product
