Almost got a demo ready for release but I need an artist to work with

Hi

So I've almost finished a demo of an anime inspired game. It should be ready to release before the end of the year, I've done all the game design, and programming, and I also have an amazing sound engineer on board(he did the music for silent hill!).

Heres a video of the demo -

At the moment the current version has template art work (and sound, but thats being replaced as we speak) I still need to replace the art though.
I've been told I should look for an illustrator AND sprite artist which makes sense, do you agree?

Does anyone have any recommendations on where might be the best place to start looking for an artist/illustrator, would any of you be interested?(ideally commissioned based)?
I'm based in London, if thats of any use.
Also please note the video below is full of template images/sounds that will all be replaced before release.

Drop me a line if you're interested!
