I would say what you have now is fine. Ultimately, the important parts of the licensing/attribution is giving proper credit to the work of others. If you took someone's copyrighted art and used it without permission, they could send Wikia a takedown notice. For the image you're using though, I think you've put enough work into showing the sources for all the parts.
