Thanks so much, first time taking fully drawing someone seriously.

assuming this is a study

Smart choice to start BW (you could take it further by using less values) and to use a "simple" reference. realism is a huge area of study so you don't want to overwhelm yourself. My go-to advice is zoom out often / look at the thumbnail. It is good at exposing "flaws". E.g. the chest is more uniformly lit in the ref.

while you capture a lot of lighting and the anatomy, the expression is different. i think that is striking in the ref, and worth capturing. goes to show that a minimal composition carries a lot of complexities. shading, expression, textures, glow/reflectivity, posture, facial proportions, dimensionality (cloth wrapping around the sphere that is her head). do you think you captured what you wanted to capture?

studies focusing on capturing drapery/clothing folds would help you. Most energy went into the face i think.

The shapes in the top half are satisfying. Imo you don't just go through the motions, you aim to reach a certain feel that brings you joy. Overall great job.

Oh, I didn't see ref when I commented. A very nice draw!

Thanks guys! It means a lot to get feedback.
@luv2 I am keeping the dots jaja. I like them and was recently watching Puss in Boots and their amazing, scratchy animation. I fell in love. Not to mention I also adore Spider-man into the Spider-verse and their equally, if not, more scratchy smear-frame, animation and not to mention those juicy lines they add on top of the 3-D models. Just, ah, chef's kiss. I like the dither. And I'm a sucker for animation. I lean more towards that than realism, so adding the half-tones is a little of my touch.

@bitbof I have watched a few videos and they encourage references with good, contrasting lighting for drawing portraits (and many things, for that matter), I thought this was a great time to put that info into use.
I did zoom out quite often, but I agree, the tone for her chest area was not a perfect match. The expression, oof. It wasn't until my family member pointed out that her face was tilted and open-mouthed. But I was too tired and too lazy to alter it. Jejeje. Since I didn't get the tilt and positioning of her face in my initial sketch, I feel like it did affect the draping and expression in the end. I do acknowledge that the end product doesn't carry what the referenced did. I did spend more time in the face, I was just too excited!
Nonetheless, I had a good time drawing this, I learned a lot. To be honest, I just wanted to see if I could draw a face that make people say, "Yep, that's a person."

Very nice :)

Excuse me mrs. nutella, but what technique/ tools do you use for shading in kleki?

@susu, I normally go in with flats and block out each part with hard shadows and highlights. Once I get a good idea of how and where the light hits, and where it doesn't, I use the airbrush (the one next to the first brush, because I don't now what else to call it) and change its setting to 100% opacity and blending to 100% as well.
I set it to 100% for opacity because I do own an apple pencil, which supports pressure sensitivity, but if you don't, I suggest 60% or lower so the blending doesn't overboard. Then I see how it looks like compared to my reference and add or remove the highlight/shadow with my mid-tone with the first brush set to low opacity and the square nib. I repeat the process until I am satisfied or rage-quit. I hope this helps!
