When it comes down to it, the work put out by this shop is actually quite good indeed. Marty does know what he's doing, when it comes to art. If I were to have him do something, I probably would have it be a custom piece. He does gorgeous old school pin up girls that are quite admirable, and his shading is really quite gorgeous. His cartoonish realism is really quite strong. I'm not sure I would trust him with a portrait, but would with a very idealized female figure.
Keep in mind that he's extremely religious and isn't a formally trained artist. You can see his paintings here: <a href="/redir?url=http%3A%2F%2Fmartyholcomb.net%2Findex.php&s=84ce4908c1c2b426807ff9e7571e606004f4a13414a296141e8fb31d9fda9976" target="_blank" rel="nofollow">http://martyholcomb.net/…</a>.
