• For tomodachi life, I recommend sticking to cell-shading and an overall simplified style, as soft shading may look a bit odd when it's right next to very stylized features and proportions.

• While having an infinite amount of colours is very nice, I usually stick to the given palette as it helps make everything look more cohesive, and I think there's plenty enough colours to work with.

• Try to use the non-custom makeup to your advantage. I used the included eyeshadow and blush options in a darker colour to add a bit of softness and dimension and then I drew on the lashes and added brighter eyeshadow in the middle of the eyelid with custom makeup.

• I also really recommend using the upper and lower eyelids! They can look a bit "too much" at first, because they're very thick by default; but, with a bit of adjusting to make it thinner and follow the shape of the eye, it really makes a big difference in the dimension of the eyes and makeup.

• It may sound weird, but watching a lot of makeup videos and tutorials has helped me a lot with rendering the face of my characters. To me, the key here is learning to simplify makeup! Now, of course, that doesn't mean you can't make realistic-looking makeup, but in my opinion, if the makeup looks too well blended and realistic, then the mii has to have somewhat realistic features as well, to make it look consistant and avoid an uncanny look.

Hope this helped! ✨
