I was toying around with Mine-Imator and while trying to create a creepy scene with a giant spider, I found something in Minecraft that wasn't in Mine-Imator: Glowing Red Eyes. In the dark, spiders have the red eyes on their skin glowing in the dark and are clearly visible to the player. (Go to a dark area and spawn a spider if you don't know this.)
Its a very minor problem, but the possibilities you could do with the glowing eyes onto other skins is a great idea. Imagine the possibilities: Glowing creeper eyes? Glowing herobrine eyes? Glowing redstone? Glowing characters??? Its a simple thing to give some skins a glowing eye effect, but it could go further than that. If the problem is I have an older version of Mine-Imator and spiders do have glowing red eyes please correct me, but besides that what do you guys think about the glowing skins concept?
