Mitsutaka,
I have this figure in my painting queue. You've done a wonderful job painting this nice sculpt. If I had to make one observation it would be that Boudicca was famous for her Bright red hair.
Here is an exerpt from a history written by Dio Cassius:
"She was huge of frame, terrifying of aspect, and with a harsh voice. A great mass of bright red hair fell to her knees: She wore a great twisted golden necklace, and a tunic of many colors, over which was a thick mantle, fastened by a brooch. Now she grasped a spear, to strike fear into all who watched her...…"
Other than that I think you did an outstanding job on the figure.
Cheers,
Mark
