Sorry it's taken a while to get back to you - I don't tend to check here very often. I'd be happy to send over the backgrounds and sprites I've produced, (minus a couple I'm holding back for if I ever finish the episode). My time is extremely limited, so unfortunately I'm not able to offer much beyond that.
To be honest, my plan was always to basically produce the main areas of the ship and just drop them onto the AGS community anyway to see if anyone wanted to mess around with them, so don't feel guilty about asking.
Let me know your email address, either here or give me a prod on Twitter (@nwheeler_cmp) and I'll try and send them over when I have time.
