AD Vector Mermaid Seamless Pattern

[Foxi]

Hi all,I really like Affinity Designer but the more features arrive, the more complicated is becomes.. There is a new challenge for me and Affinity Designer for which I would need your help and ideas:
Creating a mermaid digital paper as a seamless repeating pattern.
I got an at least basic version of the attached one  (no glitter, no lightning etc.) but due to the shadows it wasn't seamless on the vertical.

If seamless isn't possible due to the different lightning effects of my sample picture attached, how could I achieve anyway the digital paper mermaid look of my sample?

Important: It definitely has to be scalable vector, no copied images etc..

Thanks a lot in advance. I'm looking so forward to your help and your ideas!

Quick play around, lots of symbols and groups used an image for the texture.

Hi Firstdefence,

Thank you very much for your quick reply! That's already a great base! Good idea working with symbols and a gradient (due to the gradient we avoid shadow repeating problems)!!
I would have to replace the "yellow skin"-file with vector file looking similar and everything would be vector, right?

Do you have an idea how to achieve this colour-changing-effect in a simple way? 

Best wishes,

Foxi

You could try dragging out various shapes over top of it and playing with the opacity and the various blend modes.
