Hey, @nahgul, sorry I’m picking up a bit late! I agree with @Paige’s considerate feedback - shape design looks pretty good, and it should be a matter of adjusting the values to help fix what you feel might be off. I’d also soften the fills a bit more, perhaps make the tones look more uniform especially on the background, since the strong pencil texture there can become a bit distracting and even mud up the overall impression of the drawing. The cup on the right and the wing of what seems to be a mug on the far left have much softer fills, so you could try keeping that same logic for the backdrop as well. Since you’ve created this post a couple of months ago, I suppose you must be done with this drawing already? Well, anyway, hope this can at least be helpful as something to keep in mind for future work. Best regards!

May I ask: what do you think needs to be fixed about it? My opinion: It's very good! You nailed the shape of that vase. I think the leaves look nice. They're better than the reference. The heavy, complex shading makes the vase dark and irregular, in contrast to the glass in the reference which is smooth and translucent. I preferred the reference's clean look because the attractive silhouette of the vase stood out more.
