Hmm... how's this? The eye's made up of two different colours so I couldn't exactly match the flowers, but I think it looks a lot better.
Much better!
it's not about matching
all, but about the color variance you have in the composition; in that drawing, for example, you have several greens, whites and browns, with an almost indistinguishable touch of blue and magenta as an accent.
Magenta is stronger so it compensates its lack of ubiquity relative to the more subdued greens and browns. But the red of the chest piece and a little brown in the eye feel out of place, since they're farther away from your other colors, and they're ideal points for an accent, just like you did with the flowers.
Compare it to
servine, to see what I mean; a couple of shades of yellow, a few shades of green, and the red of the eye and petals as accent; I didn't want the eye
alone to draw attention, so I used the petals to balance the color throughout the composition, which is what you would do with the eye and the chest in this case.
