Hi, Mary! Your sketch is amazing
... And I'd loved to know more about it
For, at first glance, this floral pattern seems to me a wonderful example of 'Art Nouveau', not post-impressionism... Sure, there are some common features between the styles (all the more so the former gives birth to the latter). I beg You pardon, of course, l'm far from connoisseur
, so I can't state it doesn't look like Van Gogh... Perhaps, You can bate my curiosity just mentioning, which particular canvases have inspired You to sketch
Anyway, such a ring would look great!
Best of luck!
ring: Vincent van Gogh
