This looks lovely! A lot of the rendering is very sensitively handled; it'd be really easy to go overboard on the halftones here but didn't which is great. I half-agree with the other comments about the darker values; in a fully realistic scenario that would be true, but there's also a lot to be said for intentionally high-key images and clamping your shadow values for clarity. Personally it doesn't bother me, but it's a subjective choice depending on your intention for the piece! The main thing I would probably point out is the eyes aren't handled quite as intentionally as the other features, there's a bit of structure lacking in the brow, and I would avoid drawing the eyelashes as individual strands, but rather define them as soft shapes that indicate the curve of the lashes. Also the position of the highlight feels a bit off to me, as the lid has thickness that would block a highlight from hitting that high up on the eye, I would probably lower it a touch and maybe shrink it. Also don't forget that the iris itself is concave, so the "peak" of the light on the iris will be on the opposite side of your light source. Keep up the good work! :D

Hey there! Your rendering is amazing! I feel like you are missing your darkest values. Ambient occlusion and core shadows should be darker. If you get your core shadows right, that would make your reflected lights much more prominent which will help your form a lot. Right now it's a bit flat (for example on the fingers). Other than that I haven't got much to say. Maybe make her left eye a bit darker, right now it's just as bright as the one in light. Keep up the good work! :)

The drawing is pretty good. Proportions look correct. To bring it up a notch you should add the darkest of values somewhere in there. The dark black in the signature should be in the drawing too so as to make the range of tones wider and more varied.

Hey it generally looks very good, the rendering is smooth and slick. I like how you finished the hair. The mouth looks a little small though, and the neck a little thin. You might want to overlay over the reference if you haven't already. Good Job!
