Emo kid skins
Random "teen in hoodie" skins, especially the ones with the checkered mask
"Girl" skins (nothing wrong with girls) they use almost the EXACT SAME PATTERN FOR EVERY SINGLE ONE!
I agree with a lot of you especially on the girl skins. Recolors with virtually no shading or realism. I collect skins for the NPC plugin on my server and realism is what I try to find. Seems that male skins have WAY more variety and realism than all the redone anime-faced girl ones out there. They're almost all redone from that blue and black striped shirted one. Change the hair/eye color and away they go.
You don't really think about it a lot until you have to get a lot of them together to use in the environment in your world. Then you realize just how much alike they all look. I refuse to download ANYTHING in a hoodie with headphones or poor shading anymore.
Then you come across THE AWESOME.... I have some amazing skins, so realistically shaded that they are creepily real. You have to look twice. There are definitely some bad ones, but WOW are there some good ones.
I actually use a HEAVILY MODIFIED slime in a hoodie, but for holidays I customize it. At least get festive! Although it is annoying, it sometimes looks unoriginal but isnt. People embrace their skins, like I do. Gotta hate youtuber-based skins, and hate youtuber-themed accounts. Do something original. Also numbers in names and the Xx(Name)xX annoys me.
I make skins and post them on the Skindex, so I'm on there a lot, and I see like 10 of the same design every day. My brother has one of those with the hoodie, and it has a creeper face on the back, with a checkerboard pattern thing covering the mouth and headphones. Talk about no taste...
Guilty as charged... I have Katniss Everdeen skin. As if there isn't shortage of those running around. I would make my own but I SUCK at it. Some of them aren't creative at all which really bothers me. I mean, some of the overused ones (like mine) are okay because some put the time and effort into a skin that is actually something. I really hate the outline skins because of this. They strike me as lazy.
It's not necessarily the skins; it's the fact that they are common. Oh, and yes, I know this topic is titled for overused skins (not saying anyone is wrong for listing such things), but some people seem to extending the fact that they are common to them being bad, when that's both a separate and more subjective matter.
So, uh, fear my overly desperate attempt to be cute and such, rawr. Rawr!
Think about it though. Wouldn't it be extremely boring if every skin had to follow the same rules, especially a more realistic set of them that allowed for no exaggerations (realism, of all styles, dictating Minecraft seems so questionable anyway)? People are basically already complaining about certain trends and templates taking over, and yet they suggest completely doing away with certain styles/aspects of skins as the answer? That will make it worse, no? Or maybe they're just trying to feel better about having a more original and/or self-made skin? Maybe they just want something "better" to be what's more common? I don't know; it's a little hard to tell.
The matter is, there is only so much you can do with the limited number of pixels. For better or worse (I admit, there is a lot of monotony), this is what we have, but limiting the scope even further only perpetuates things. You can't forcefully spread it even because different people have different tastes, and some will also gravitate towards what is popular, either because they see it and like that trend (like I did, and I don't deny that), or, perhaps a larger thing is, most are just people surfing the Skindex or Planet Minecraft and see common themes and want something that's "in". As easy as it is, not everyone cares to make their own.
But, uh, fear my cuteness, and, uh, down with the hoodies and headphones and small chins and big eyes and long hair!
