Like Samohtep, I do some work for a print shop, but we do specialise in fine art printing. Generally, we would advise 300dpi as the minimum, but you also have to remember that a print of that size would sell in an art gallery for $200-300, depending on the reputation of the artist. People spending that kind of money have the right to expect an excellent reproduction.
It doesn't look like your print is heavy on sharp, fine detail, so you've probably gotten away with the lower resolution. :thumbsup
And nice work btw!
