Hi there, if you're looking for more choices I would be interested. I do digital and pixel art but I would assume for concept art you'd want digital. You can find some of my work on my deviant art gallery.

I usually charge the following for digital art:

up to 275x200 £10 GBP each

up to 375x300: £13 GBP each

If you wanted it significantly smaller or larger than these, we can discuss further between us.

I would be willing to cut the costs in half for an upfront fee if I were to also get shared revenue, however if for any reason it were to be cancelled I would expect the full price. But this is also up for discussion if you have something in mind.

You can contact me on here or email: laurel.tompkins@yahoo.co.uk
