Graphics for equestrian pacman clone game

We are currently prototyping a pacman game themed for horse people and have therefore some coder-made (i.e. ugly) test sprites, backgrounds etc. that must be replaced before public display. The game is to be of very low cost to the end user (actually we are planning on giving it for free on downloads and 5-10 USD on CD-copy). What we need: *) 1xTitle image "The hay race game" (1024x1024) *) 2xCharacter sprite displaying a girl/boy wearing tight pants, black boots, black helmet and t-shirt. (512x512) *) 2x"Monster character" i.e. a dark cloud with rain and a smile on it (512x512) *) 1xHay sprite (i.e. sprite for the item that turns monsters into eatable-dummies) (256x256) *) 1xOat-grain sprite (i.e. sprite for the items that indicates where the player has already been) *) 1xGrass background image (1024x1024) *) 1xSet of tiles that can be used for constructing "infrastructure", i.e. horizontal, vertical, left- and right turns and intersection dirt-road. (256x256) The prefed graphic style is "cartoonish" perhaps like Thelwells pony stories (google for it). Everything must be delivered in Photoshop PSD format for later editing. Please send samples of previous work or link to references that demonstrate your skills (preferably for work with "cartoonish" work).
