im looking for a way to render the eyes a bit more

[solemn frost]

You can add a waterline to the eyes, you can add shadow to the eyeball because the eyelid puts a shadow onto the eyes, the green eyes need to have like more details, I think you can start off with covering it with dark green then at the bottom adding the light green then shifting the hue left or right from the color wheel then using that to add a bit of detail

Using a bit of gradients can help (all of this is just how I render you don't need to follow it word for word unless you want to)

Just a rough sketch of what I mean, ig the waterline didn't match your artstyle so I just did the rest of it

Use multiple colors and to color the eye instead of just two , letting the lightest part be at the bottom and shading the rest like a pupil/circle.
