Frame test

I've been pondering whether I should buy a frame for Larmes de Joie au Jardin des Géantes, or make one myself. The question of which frame style to pick from must be taken seriously. I've been hesitating between a dark, baroque frame that would enhance the luminosity of the painting. Or, a heavy, rusty metallic frame that would respond to the reddish armatures of the garden's dome, and would be also consistent with the one I already built with my father for Sous la Rouille.
The picture above is a sample photographed at the framing shop tested against a print of the painting. The estimate I asked for said slightly more than 800€, which is quite an amount.*Sigh* ...
