If people don't mind you taking their graphics from their mods, you could look for the
Halls of the Underkings Mod for dwarves,
Forest of Loren Mod for elves, and
Orcish Empire Mod for orcs.
I most people have their shrapnel names located with their mods so you ask for permission. I'd like to learn how to mod graphics, but I lack the artistic capabilitly to do anything from scratch.
