This creature is such an interesting combination. I think it's largely due to the fact it's two animals that really don't seem like a good combination but the way you implemented the octopus tentacles into the mane and gave it such a nice color balance, the design works super nicely. It looks interesting enough without coming off as too "Hentai-y" but still has a bit of a slimy factor that would probably make me hesitate to touch those gelatinous tentacles haha. Great design!
