Hello Thomas.
I'm always glad to help. But I don't understand your question. You can more specifically clarify - what kind of assets are we talking about? If you mean "highlight" or "glow lance" etc. is just painted textures. The plume from the head of the tiger (in final animation) it's standard effect in "Spine". Additional applications or arts downloaded from the Internet, I did not use, if you about it.
I open to freelancing. All depends on your offer.
