I think it is looking really nice

Hi @eleftheria_arts I think the crosshatching technique looks great, I'm especially impressed with how soft you were able to get some of those shadows (like in the cheek area) using this method. I do think that the handling of detail on the hair could be simplified to put a greater emphasis on the face. Additionally, there are some minor areas where the light/shadow seems a bit inconsistent. For example, there are some really dark occlusion shadows under the nose and where the nose meets the cheek, but they should probably be kept lighter because the occlusion of light in those areas aren't that dark. Additionally, there is a patch of light hitting the shadow of her cheek, which I also think should be grouped into the shadows by making the values just slightly darker. Even if the reference does happen to make those values that bright, you can design your own image for better clarity. Hope this helps! Let me know if there is anything that I can clear up for you

IMHO your piece is great. I only would point out that the shadow below her neck/beginning of her chest looks like hair, which I assume is not your intention. I also would say that something looks a little off with the overall proportions of the head; too big? too wide? I am not sure.

One thing to do to prevent a hairy, scratchy look with hatching is to follow the forms like I see you've done with some of yours. Something about the silhouette of the front of her face feels wrong to me. I think part of it might be that the far side of the cheek is so light that it's blending in with the background so it makes it look off. The hair looks really nice.
