I'm a technical illustrator/artist/photographer living in Smiths Creek, MI.
One of the things I do is paint on birdhouses scenes of things I like. These might end up at a local feed store or sold directly to a customer. I always lull down art and photos that I can use for reference. Your shipping pieces seemed like they would be very good in painting generic ships and their details.
I am presently back in college on-line at The Art Institute of Pittsburg On-Line and taking my last two classes to graduate with a Design Diploma.
If I have not said it, I think your pieces are very good and very detailed.
