Hi.
Just real quick, this is gonna be the next drawing and I'll add the next details:
-Details for Celestia's hair and Sunset's hair
-Details for their eyes
-Refining their nipples
-Refining the pool and the water
-Adding shadows and occlusion (specially for the pool design so it wouldn't be visually confusing)
-A light from the top side of the drawing, focusing on Celestia and Sunset
-A more detailed wall for the background
-Blushed faces
-Layers of curves, color balance and hue/saturation to refine the color composition
Also more sketches




The first one is the only one that I would remake because I really don't like how I've drawn Twilight. If you take a closer look, you'll the that the circle from her head structure is a bit bigger than Tempest's. Because of that, drawing the rest of her body was confusing. And the result was also confusing, so this needs a redrawing process. But it was fun drawing Tempest's back.
I hope you like them. Tomorrow I'll show you another WIP of the next drawing.
Love,
