Good job on that artist study, figures are showing improvement, especially the breasts, youโre starting to draw them more realistically
Watch out for symbolic and white eyes in your rendered pieces. Note that when you look at a personโs face, even though you know the sclera is white, it rarely is white unless you point some strong light directly at it, it will usually be gray and shaded as a sphere within the eyelids
Also, as for the symbolic eyes, in stead of using a common shape for the eyes (like almonds) try to visualize the eye more 3 dimensional, like the lids wrapping around the sphere and their thickness - or just some lines and shapes that would otherwise suggest that type of construction (for example drawing the shadow of the upper lid and a hint of brightness of the lower lid, rather than outlining the entire palpebral aperture
Cheers!
