Can anybody help me with this hearth?

[iMilchshake]

Hey, im currently working on a pixelart hearth which i want to make with hama beads later. Can anyone help me improving the hearth? (Shading and outlining in generall)

It's going to be huge once you make it in beads, are you sure you want that?

[iMilchshake]

Yeah, thats the point. Will add some text later, supposed to be a gift for my gf^-^.

Feels like you don't need to extend that much the highligh and maybe a little of antialising could help improving it.

I'd say rework the edge shading, maybe remove it entirely and tweak the highlights for a kind of neato glass/fibreglass texture
