Very, very, very nice.
Uzurpatror, that would come in REALLY handy for the FRSet. We would need to modify them a bit, but they would be great templates for us to work on.
I was really thinking about freight wagons in these days (we have been focusing on engines so far), and your sprites would really speed up our set's completion a lot.
The cars don't look very European at first glance, but France did have some US-imported rolling stock, and your artwork would represent it very well.
So, we'd be eager to use them as templates and do some slight changes here and there to make them fit with the rest of our rolling stock better. Of course you'd be rightly credited. Deal?
Oh, and if you have other cars you're willing to share, by all means... we're always interested!
