Hmm, all I have is my tutorial tag here. Have to sift through 3 pages of stuff though ^^’ sorry, I don’t have anything more organised…

I have no idea what a tutorial on opacity would include…it’s kind of just this:

…if I had to summarise it ^^’ all it is is making a layer more or less transparent, which allows whatever is underneath to be shown or hidden. I usually use it to lessen textures on things, shadows or highlights I’ve coloured too strong, or for things like this. Other than that…yeah ^^’ sorry I can’t be more helpful, it’s not a massively in-depth thing.

I’m hoping to have restocks of the Ratchet, Lapis and Garnet charms up soon! along with 3 new designs :) just waiting on one component before I can put them together ^^’ so hopefully that comes in soon…and thanks!

I haven’t played his DLC, so no :\ same goes for Shale when I get to making an Origins set. If I ever happen to get either of those DLCs then I might, though it’s unlikely that I’ll be doing that any time soon.

_{Unlike Shale’s DLC, Sebastian’s isn’t free so that’s my guess as to why he’d often be left out :O …well that’s what I would’ve thought, don’t know though…}

I actually really want to redo the sparkly Lapis! also Jasper. But I won’t be doing those for a while ^^’ got them on my list though!…my really long list :\

Nope, I do not do requests. I was thinking about taking a couple of little ones though as part of another thing, but I’ll post more about that later when I’m sure I have the time to complete them!

The Animator’s Survival Kit is a pretty good resource for a lot of the basics, we used excerpts from it at Uni and I know people(myself included) who find it useful as a refresher.

Other than that study everything, study animations, reference videos, and the movement around you every day. Also when I say study, really I just mean take notice of stuff…though sitting down and full on studying movements might work for people ^^’

And of course just animating a bunch! whenever something looks weird, usually I find it’s just a matter of trial and error with frames or approaching it differently…lots and lots of trial and error :\
