Nice illustration! Us humans have to name everything, don’t we? Even the things that don’t matter! Fun project!
For eye shapes we have round, almost round, and oval.
Almost all eyes are round, almost all are “large.” Some are “very large.” A few are “medium.”
Some are lively and alert. A lot are full... which means a lot of nothing, since I should hope the eyes are fully formed. Some are prominent, which I assume means no overarching brow.
You could use “bold” which indicates an angry eyed expression.
But I would describe the skull, saying that the skull is “projecting over the eyes.”
Also say “oval.”
