I like the Caos Dwarf scheme. I was expecting red, since that's kinda the default color, but the blue stands out nicely. Curse your skills though, since lately I've been compelled to skim through the Chaos Dwarf offerings on ebay. You're going to cost me money.
That aside the hawk riders look great as a group. I agree with your assessment of the newest sculpt. It's a touch awkward. It's a pity you couldn't have turned the head forward so it looks like she's looking at the enemy.
Great work still,
