So, the last thing I want is this to turn into any kind of argument. I have done multiple QC's so far, most of which have been rejected or altered to the point of being moot. I not particularly salty about them, so don't take it that way. I've probably spent way to much time arguing about Greninja, and while the current sprite still doesn't quite rub me the right way, I think I'll drop it here.
I think you're mostly right. Considering how little QCing actually is is needed, I probably don't have much left to contribute. I'll still be visiting the thread and putting in my two cents, but I doubt I'll be contributing that much, if at all.
So, a few side notes I wanted to make:
I haven't asked until now on fear of sounding noob-ish, but what does QC stand for? I've never heard the term before.
I've tried using the "completed spites" link to look for sprites that need QCing, but I noticed that it's not up to date. Could you please update it?
I noticed that Furfrou's sprite is really big, as it stands at 62 pixels tall. As much as I hate to say it, considering that current sprite is amazing, but it probably needs to be sized down. I think I mentioned this before, but the same thing applies to Diancie. It's also 62 pixels tall, and just looks funny when it's as tall as Yveltal.
