Not yet, I'll probably make one tonight so keep a look out for it on this board.
Also, I'll probably do away with the 'teacher' idea unless I can get some really expert skinners on here to help judge who should be a teacher and who shouldn't be. So as of now everyone can give advice. Of course, though, I'll expect everyone who gives advice to do it in a polite and professional manner...I really don't want the thread to devolve into a flame war with people being rude and arguing about skins and whatnot. So, yeah, I should have it done today. If you know any expert skinners it would be great if you could ask if they'd consider helping out here!

ohhh could i be a teacher on the new post? and maybe you could help me with shadeing like somone previously said i couldnt shade good to save my life

The original 'teachers' don't seem to be posting anymore, unfortunately, so I think it's more of a free-for-all of advice giving at this point. You can certainly give advice if you want.

what do you think about this ? some feedback would be cool

They both look pretty nice, actually. To Theminemaster, I've having a bit of trouble figuring out what that bright red thing is on his back and why it's brighter than the rest of the red on his skin, so I guess making that clearer would be my suggestion.
To Nergal, I like the way you blended the white of the fur into the orange. My main suggestion would be adding some shading to his arms, legs and head like you did with the back of his arms. Right now it looks a bit flat. Also, it took me a while to realize that the thing on his back was his tail. Perhaps try shading it with highlights on one side and shadows on the other to make it look more 3D.

I hope that helps! Hopefully an expert skinner or two will show up to help with advice...

I'd suggest adding some more detail and then attempting some shading (look up 'shading tutorial' if you don't know what to do). Right now your skin is just flat blocks of color. I understand you're a new skinner though, so definitely look at some tutorials and try to challenge yourself with your skins.

ParkourManiacI am using MCSkin3D and I would like some help with shading. Also, I am finding it hard to make detailed skins on the lowest resolution. I would do it on a higher resolution but it won't let me upload on Planet Minecraft.

Use either the burn/dodge tool or the lighten/darken tool to shade and highlight your skins. My skins were all shaded in MCSkin3D using those tools, if that helps you. As for details, you sort of need to look at the big picture of what you're trying to skin. Some details are crucial to making look like what it's supposed to, some aren't necessary. I guess for example, if I was making a cat skin I wouldn't worry about small details like nostrils or the whiskers above the eyes, but I would include important details like the whiskers on the side of his face and paw pads. That way, it's still recognizable as a cat without having pack in as much detail as possible. I hope that makes sense.

kenniksIm having ploblem with shading..a lot.

Whenever i try to shade from light to dark or dark to light,it always goes so random and messy.Check out my latest "Warrior girl" skin for what im talking about.All the shade just goes out of it's place.Any tips or solution?

Honestly, I think your 'warrior girl' is pretty nice. I guess I'd suggest simplifying your shading down to the most essential shadows and highlights, and then slowly building up more detailed shading from there. Also, if I also have problems with shading I'll look to the great skinners for examples and try to incorporate their techniques with my own.

Please, there are tutorials on this topic.

Shading, shading, shading.

Hi, you should add a bit more shading in small areas and make it less ruff.

The shading is really nice. It might just be me, but the colors of the coat are a bit muddy looking, you should try playing around with those a bit.

The left hat section is immediately to the right of the back of the head, the front hat section is to the right of the left hat section, the right hat section is to the right of the front hat section, and the back hat section is to the right of the left hat section. The top hat section is directly above the front hat section, and the bottom hat section is directly above the right hat section. Here's a picture if that's not clear: http://i.imgur.com/y5GJ5.jpg
