Spoiler!

Hey guys, I've recently got into coloring lineart again, so I figured now would be a better time than any to post a link to my Pixiv account. I don't know how long I'll stick with it, but I'd appreciate some input nevertheless. I'd like to improve, but I don't know a damn thing about shading, lighting, or any of that, so if any of you guys could help me to understand how to add shading so my colorings don't look so plain, I'd appreciate it!

Also, there's a problem I've encountered recently with some lineart. Normally, I can just use the wand tool to select an area, then fill it in, and eventually color the whole picture piece by piece like that. However, on some of the lineart I have, the first layer is locked and I can't remove the lock, nor can I color it by using the wand tool. I've tried creating a duplicate layer, then deleting the locked one and doing it that way, but it just doesn't work.

Normally, I would just delete everything with the wand tool and make it transparent, then fill it in with white and start adding new layers for separate parts of the picture (i.e. eyes, hair, skin, clothing, etc.). If the picture is already transparent, then that makes things a bit easier for me. It seems the only way I'll be able to color some of these linearts is manually going over every inch of it with a brush, but surely there's a better way... Right?

Anyway, if some of the art buffs around here could shed some light on that, that would be great! I'll be editing this post with my newest work every time I finish one, so be sure to check back periodically. Oh, and feel free to rate and/or comment on my pictures through my Pixiv page as well if you've got an account. Thanks!
