I usually hate wall posts like these, that encourage people to subscribe to someone else somewhat baselessly, but I really enjoy the idea behind them, and I want to do one of my own, mixed in with hopefully some appealing arguments for following said skinner, instead of just asking you to follow them. Here goes:

habearry

Habearry is a skinner, who experiments with colours plenty, sometimes to the extend of going overboard with it. Their shading would be mixture of what I call a classic teen skin style with a more gradient (colour rich approach). This provides for an interesting style, that I cannot wait to see how develops. Curiously perhaps their most interesting stuff is posted in wall posts (and perhaps on their skindex idk) so keep an eye out for that.

Boaty is a skinner of many styles, which gives you a large variety of content to look at. I'd like to point out Boaty's keen eye for designs. For this reason, stay keen on Boaty's work and let them know which styles you like, and what you'd like to see from them, as they can deliver very well on feedback!

Reluctantly including kitt-chan here: Reluctantly due to the fact that Kitt is not really that underrated. Kitt chan is another somewhat 'gradient' skinner who provides great quality content in a variety of styles, and I highly recommend checking it out. Kitt-chan is already very profecient with colours and shading.

mirabilia

Eloise I know has a following on skindex, and I do not know the differences between what is posted there and here. I will say, that Eloise has a few tricks up her sleeve. Eloise is a good example of a primarily girl teen skin creator who has shown capability of trying more abstract concepts; and this I think can make for quite an interesting ride if you follow Eloise. As a form of minor critique; it might be beneficial to cut down on contrast and "template"-like shading in some of your skins eloise, as I think that'll speed up your profress significantly. Contrast is good, but it can also get overbearing quickly - sometimes you want some 'negative space' on your skins without heavy contrast (x

WhatToMake

Genuinely, this guy is the entire package: Shading style is a check, colouring is a check and designs are great too, highly recommend checking him out. Doesn't appear to be active lately, but when they are, you're practically guaranteed quality!

Vaedak

Another person who has the entire package, also insanely good mob skins. Do check this one out!

Of course there are many more, and maybe one time I will get around to mentioning them. I am not that good at keeping up with PMC skinners anymore, but here are at least some that are worth giving a look (x Cheers

Since launching PMCSkin3D, our skin editor has supported the creation of HD skins...

Today, you can publish HD PLAYER skins to the PMC skins section!
While they are listed alongside standard definition skins, they are easily identifiable and filtered using the "Format" filter. We support 128x128 resolution because it's officially supported by the Bedrock Edition.

Besides the higher resolution, it's easy to identify HD skins by their isometric preview and label "HD Bedrock Minecraft Skin". HD skins can only be downloaded. We are unable to support remote change or papercraft.

Game Version Support
HD skins are officially supported by the Minecraft Bedrock Edition and unofficially supported in Minecraft Java Edition with the use of Optifine the MorePlayerModels mod.

Note: If you've already published your HD player skins in a blog, you can republish them without taking down your blog. It's up to you.
