>Lineart drawn at a high resolution with a relatively thin brush
>body colors have a warm, inviting palette. Even the Black bikini top has pinkish hues in it. The blue of the background contrasts with the warm foreground, making it pop.
>Shading done with a round brush to give it a smooth look. Most of the shadows are large and simple, which adds to the aesthetic appeal (ex. the shadows on the stomachs). Additional shading details are donw with a soft brush with a color very similar to the base skin tone, and are done sparingly (ex. The shadow on the left girl's deltoid and her abdominals) a hard round brush is used to add a few subtle highlights (ex. the spots of light on the breasts, the shoulders, and the noses)
>Lineart is colored in with a slipping/masking layer to match the warm hues of the skin
