The shoulder especially is fantastic!
a few pointers:
1) his pose looks like he is about to sit down for a dump ;)
2) The dragon faces on the side of the hammer are cool, but maby if you made the hammer in the shape of a broad dragonhead?
3) The cloak looks like you spend 2 mins on it as does the "shoes"
seeing this model makes me wish i collected salamanders instead of my blood angels, although his cloakc appears to be cut short on his right shoulder (looking from his point of veiw) and the spikes that protroud from his cloak look out of place... i dont know maybe they should point downwards. hes also missing a gun
Great miniture, great sculpting
