It's already a great start! I love the fluidity and clarity of the energy. The thing I'd recommend is going for longer, more confident strokes, especially keeping an eye out for CSI lines (which are lines that resemble the shape of those letters, more info can be found here along with some great warm-up exercises: 6 Habits for Good Line Quality). By bringing in clearer strokes, it'll help reinforce the great expression you already have in these gestures -- keep up the good work! :)

Nice work!

Looks pretty good! I would just recommend layering a bit more to develop the darkness of the values, especially around the middle, so they're more clear and different from one another. It's a small difference but it can help with clarity, especially for the shadows on the face, but you're definitely doing great so far! :)

You've got a great lay-in already, I think it's just a matter of pushing your value range further. Using more of the darker side of the value range can help further clarify the shadow and form of the subject. Especially for key areas, such as the face, using dark details can help bring more focus and create a hierarchy to organize the drawing. Keep it up, you got this!

Lovely work! This depends more on the style you want to go for, but for something more painterly, I would recommend lowering the opacity for the linework and using the values you already laid down to describe the form instead. Especially with the silhouette outline, the contrast between the dark background and lighter skin tones alone will allow the form to read on its own, and pushing the background to be a bit darker can help make it even clearer. Using shadows to define edges can also be of great help. It's already looking very good, so this depends on the final style you want to achieve -- keep up the great work :)

Hey there! This looks amazing already, really nice work! I think a point to look at would be how contrast is created throughout the piece, especially through value and edges. There's already a great blending and use of softer edges as things get further from the focal point of the face, but reinforcing the contrast at the face, especially the eyes, could help make the final pop. This could be through more defined edges and a use of darker value for the eyelashes/irises, for example. I would also caution watching out for unintended areas of high contrast, for example the shadow area near the elbows or the decorative hem by her legs, as the high value contrast and sharp edges could lead the eye there more than needed. This is a great piece nonetheless, so these smaller points could help push it just a bit further -- hope this helps and keep up the great work! :D

Awesome work Marco! I especially love the stylization, it feels very lively and cheerful! :)

Very lovely! You have already a great description of form, the only thing I would recommend is further pushing the definition a bit with some contrast. You could even achieve this by only adding a bit of darker value in the current darkest areas, making it really pop and read more clearly. Great work nonetheless! :)

Nice work! When it comes to rounded objects like the lamp, drawing through as if the object were transparent can help place the curves of the edges with more precision and make it easier to follow the perspective of the drawing. Also, adding some dimension to objects even when they are thinner, like the paintings on the wall, helps sell the groundedness of the scene. You're definitely on the right track, keep up the good work :)
