Hello ZELL_VN!

First of all, I think you have done a great job!

I find your leaves really good and also your branches, maybe making a bigger separation between the ellipses will help you see better the branch. But what I said before, they are fine.

I liked the flowers you picked, you treated them delicately and the construction is really working.

The aloe has complex leaves, I also struggled with them. Your drawing reads well in 3d space.

About the grapes, they just needed to be treated more subtle with contact shadows.

Good job! Keep patience, keep your brain active while drawing and go on!
