To follow up my new reference sheet, here is an alternate version with a natural color palette! I adore the teal and mint green of my sona's original design, but I wanted an option that feels more connected to nature that I can utilize in more natural settings; an option that can fit cohesively into more realistic scenes and environments.

The original design with the teal and mint is still Delta's main design. This is just a fun alternative, and I am looking forward to drawing her like this more!
