Strong points: rich, dark colors to contrast the light/nectar effects — love the read of her blouse. The almost angelic halo is interesting as well, though not sure of the meaning (if any). Her pose is great and again works to provide an angelic quality.
Weak points: the hummingbird is a bit too undefined especially in the head. This gives it a bug/hummingbird/faerie feel, but it would be nice to have just a bit more detail. The abstract dark vertical lines to her left give texture but don't really convey anything, so they look more like scribbles than elements.
Gritty textures really bring the glory of the interaction into crystal clear focus. The dark colors makes me think that this hummingbird is pollinating the soul of this lovely maiden. Whimsical without being to trite. Your minimal style and rich reds bring such warmth to an otherwise desperate women. Your conceptual work is always so great- And the layering of patterns in the background really are a nice touch. I can honestly say this is true to your style... Don't change a thing!! I really feel this and can not wait to see what else you have in store!!! MH
