kirra, This is an outstanding offer you have put out there, I am sure it will keep you beyond busy and help build your portfolio. I am one that will surely keep you in mind, Im good at programming, but when it comes to art I couldn't draw a stick figure. :)
If your still offering your services, do you have experience creating top down Gauntlet Style atmosphere and characters? see below:

What about the actual background itself? Rooms, Tile design in that art style etc..
thanks so much.
