This is my reference for these characters.

!The colour pallets on this reference sheet are there so I could easily re-create the same shades of colour every time I draw the characters because of reasons, however if I commission someone to draw one of them, you don't have to follow the pallet strictly its just here as a guide for people who draw the characters!

The brown one is my main character and OC while the blue one is his friend.

They both have markings under their eye, the brown ones marking resembles the horns on top of his eye whilst the blue ones marking reminds me of something circuit-like
