Hi Ghostwolf,
Your project and your methods sound great, and I would love to offer my help, but I am just a starting pixel artist. I am currently working on a tile set for a dungeon side-scroller. If you want to mess around with that, then let me know. I will try to finish some stuff to put online for viewing. To be honest, I could use someone to tell me what tiles are usable and which ones are not.
My next project will probably be to create top-down tiles, maybe even isometrics, so hopefully I will catch up with you. :)
If you need any help with proofreading text, translations, or dialogues (as you wrote), then feel free to contact me here.
Good luck man!
