[@Nemaisare] [url=https://www.reddit.com/r/ImaginarySteampunk/]ImaginarySteampunk[/url] on Reddit -- as well as probably the general Steampunk sub -- has cool things. Also Tumblr Steampunk Art tag. [url=https://www.artstation.com/]ArtStation[/url] is great but not as easy to find exactly what you want. I also have my own [url=http://www.juxtapost.com/site/permlink/33a64860-1239-11e5-8a1e-cfaa3116ff36/postboard/characters/]Juxtapost[/url] page where I collect character art that you're welcome to use -- which reminds me that Juxtapost and Pinterest are also usable sources with the right search terms. Hope that helps!

[@Rhymer] Max is most certainly approved! :)
