Help Me Identify These

I have several character designs that I can't find credits for. They didn't come on the original image and any trace of them that I had saved on deviantart is gone. If you know who the original artist is for some of these, or even where the lines or base came from, please let me know. The first two images only have the lines "credited" as skidufond.

Yeah, lines for first two is by skicats (formerly known as skidufonds i suppose) on DeviantArt.
Lines for the last two are by x-SWC-x on dA. They both can be found here.

If you bought them on dA and the posts are gone, that'd be a bit more difficult to find the original designers. :<
Unless you bought some here? There are some designs sold here using the skicats lines if you search the name.

I'll try my best to help a little more but I doubt I can help much. D: Good luck with your search~

I think the first two were designed by Pistol?

I’m pretty sure I have a design or two on the first lines. They were done by Dayton(#21697). I wish I had my original images but I’m on my phone! But I know she used those same lines so maybe it was her. I wish you luck!

These two were designed by me. I can spot my designs a mile away lol
I couldn't find traces of them on my dA (including my old one), but I still have the psd file
for those lines, and I recognize the coloring style/poor excuse for dun leg stripes rofl
