Nice idea and great execution. I really likes how you used light and shadow to create a highlight around the face. Admittingly, i would say that i myself am not the best at materials 😅, but i still have enough fundamentals to offer some help. The main trend i am observing in your artwork is that the " Relativistic lightining " is wrong for the materials. For a starter, i believe it would help if you try to think of light and shadow in terms of relativity to other objects in the scene. The main idea is that, in a given scene, things appears " Bright " or " Dim " only due to their relative value to the other objects in the scene. Now applying this concept to help in your artwork, lets first look at the " material " part you mentioned. For shading materials , we should always ve highly aware of the relativity in the ability of the material to reflect light. Science aside, just figure out which material would be the brightest when exposed to the same amount of light. And you can go as far as to label it with numbers so you remembers that as you shade. Now due to relativistic lightining principle, the lightest thing in our scene should be the glass on nami's hand band . Second should be her vinyl jacket, specially the planes of the jacket angled toward light, third, should be nami's skin itself ( she is quite fair 🥴 ). And so on. But in your artwork, you accidentally suggested that nami is fairer then vinyl jacket. So let's fix that by making her a bit dull Next is something that's not mentioned by you, but is of a greater importance for the integrity of the realisticness in your artwork. I am observing that you have highlighted parts of her hair and the jacket that are present in the dark. And as we have discussed the effect of relative values, this suggest that that part is somehow able to recieve a amount of light equal to the planes in the absolute light, which is really confusing for the audience. This really messes up the realisticness of our artwork, so let's fix that as well by just matching the value of "dark" jacket in absolue light with values of highlight in " absolute dark " . Remember this ruke for good contrast , "the darkest value in the light, ia lighter then the lightest value in the dark "

Hi hi! Love the graphical vibe! Very cool idea and style! Painting transparent materials, such as glass, water, or clear plastics, demands more attention to layering, light, and reflection than just the color of the object. Find the location of the light source. Light is refracted by transparent objects, frequently producing a light-filled shadow on one side and a dazzling highlight on the other.Draw the shape lightly, paying particular attention to outlining its edges.Note wavy forms or distorted background features viewed through the object. Then, paint the background and any objects that will be inside or behind the transparent layer (in this case, a figure and some background). Apply a light, muted color (light grey, light blue, or tinted hue) to the translucent object's shape on a fresh layer.Reduce this layer's opacity somewhat (e.g., 10–30%).To prevent painting outside the edges, use a selection tool to fill the item inside the lines and lock transparency. Where the material is thickest or where it joins other things, transparent items have intense shadows.Paint the edges, bottom, and cracks with a low-opacity, dark hue on a "Multiply" blending layer. To make bright lines and sharp highlights, use a brush with a strong edge that is white or very light in color. The object's contours should cause reflections to warp. Hope it helps!
