Imo it doesn't really feel like the site has an overall style, just a set of standards that keeps being raised as the site grows. The site has been around for 14+ years. Each artist definitely has their own style, and it's usually easy enough to tell which artist did which sprite, because the way they do things is different than how another artist does things.
But, some of the sprite really are old! And usually that's fine, not all old things are bad. But with that age marks a period of time where things like anatomy/shading/just general definition of body parts wasn't stressed, and the color palette was limited to 16 colors, and that's including transparency. And, in my opinion, it should be ok, now that there's better knowledge out there, and there's not such a strict color limit, that artist have the ability to go back and adjust things.
And no one has to be happy about the changes, it's kind of like when a retail company decides to heavily rearrange their stores so that it takes you three times longer to find all those necessities you were dropping in to buy and now you're mad because your time was wasted having to wander around the store because the employees aren't used to it yet and had no idea where anything outside their department was. I mean, admittedly, it looks better somehow, and a few things make more sense, but the old layout was perfectly fine. The old sprite was fine, maybe not perfectly fine, but it did it's job but now the corporation has decided to change things for what the corporation thinks is better. And that's fine, but it knows not everyone is going to be 100% happy with it.
I.. hope this ramble post makes sense, lmao. I just wanted to toss my two cents to the witcher.
Also love the new changes, I'll have to nab me some Lacuas! I felt they were the weakest of the Harry Potter release despite the awesome pose because of the scales and shading. Love them now! Love the Magis too. I know seeing them so thin can be shocking, but some dog breeds(and honestly, humans) are just naturally thin, and don't normally have that much fat to them. I like the changes to the Sakuhanas, and the new Thunders are absolutely boss, although I do see how people can be upset with the horns. And I like most of the snow update, but I don't know if I really understand the new shading on the wing arm.
Lovely Lovely work from the artists, keep up the work you guys. ❤️ I appreciate you all.
