Loving it ilkke! I hope I'm not missing anything from interpreting it in terms of the eight virtues:
I think I clearly see "Sacrifice is Courage to give oneself in name of Love" in the form of the little hatch opening in the armor and the arrow striking the heart. Then I think there is also "Compassion is Love of others" since the bird is allowed to rest on the hilt of the sword. The overall posture appears to stand for "Valor, Pure Courage, standing up against risks" (also supported by the risk to get shot in the heart again, making the hatch serve another purpose).
Oh and the colors... haha, ok, should have looked at them first, they seem all tailored to support the symbolism for each virtue being depicted and the palette appears to be composed entirely of colors from that virtue system. For example the main chunk of white(the color for Spirituality) in the center and some smaller chunks of it elsewhere, fits perfect for "Spirituality is to seek Truth, Love and Courage from one's own self and the world around" and yellow being the color for Compassion supports the observation about the bird, orange the Sacrifice.
