Lovely, Ivan! You did a wonderful job with your choice of accents and colors here. The baroque swirling patterns in the corners mimic the twisting rays of the lion's mane without being exact copies. I love the subtle "ray" pattern in blue and green, shooting out from the mask...very classic and a nice addition!
My only complaint (an observation that only I would notice, probably) is that the shape of the nose was altered when you mirrored the mask image...it made the nose look small and cute instead of big and lionlike. But again, it really does not detract from the impact.
