Thanks for that feedback, this painting was a lot of work and stress, and I realised my tablet's colour profile was quite off compared to most screens and way too saturated/bright.
I may have got lazy but it wasn't an easy subject and I didn't want to stress myself out by pushing to hard to get this one perfect.
I sorted out the colours in the painting and although I researched liquid effects as Leeireo suggested I prefer to just finish it and move on for now. (but I'll still take the feedback into account for future work)
Also I just threw the environment together without much thought, I'll probably do some more studies before I think I can do them properly.
Anyway, here's the finished piece, not perfect, and far from the best I think I could achieve in the right mind frame, but finished:
