Thanks for your interest. Start your own gallery or contribute to existing ones. There are some exceptions to this scheme here and there. I don't want to say much about the paintings. They must stand or fall on their merits or demerits.
Some works employ computer art programs quite a bit.
Others are mainly by hand and scanned in. Fortunately the cost of adding memory has gone way down. If you can t afford this route, plan on working with fewer colors and at lower resolutions. Anything you can do to get more storage space, that will be of great benefit. Color images byte off a lot.
