This is Icealos eye. Their eyes are built this, because where they come from there was nearly zero light. The black absorbs what light there is and it is reflected in their eye (blah blah blah) Aliens evolve differently. Surprising that they have such a humanoid form already.
More will be said as more parts are posted.
Oh, the Icealos species belongs to me. If you do draw one then please give me credit for the species. Thanks.
Note: the bottom left section isnt curved enough. Im posting these to try and helps someone who I commissioned. The bottom left should be more curved and up more.
