I know that you don't like pinks but I used it in a way that hopefully won't bother you jiusukdm. Also! drawing those lines isn't exactly necessary, and you can simplify it.
Anyway! This is a dragon that has parts of its body made out of a weird water-like substance, and this substance can change its color depending on the dragon's mood, and can be extremely dangerous if ingested by other animals, even though it has a sweet smell.
As for my likes... umm.. I don't think I have anything in mind right now, so I guess you can do as you please? Maybe something with purple/blue... you don't have to limit your palette to those colors though.
