If you send me an email: tyler.jacob.warren@gmail.com I will send you whatever pack is missing, or having issues.
On the Pixel Style packs, the 3 packs are remasters of images found in earlier packs. I had not been creating pixel style work previously and I wanted to bring the library together in that style, so created the pixel-style packs to catch up what was already created. My later packs included pixel-style assets in them, so those monsters are not in the 3 pixel-style packs, but instead are included in the packs themselves. Hope that makes sense.
