LOL!!The Hammer looks perfect,oh man you are "God" in what you do I really admire your work skills and can't wait to play with those awesome Models!
About the Axe well for now you have very good balance Movie=Book so may be NJM is right the whole point of Dains Axe is to be somewhat unnatural to look more fearsome and mysterious so I like it in Red too! I guess Whole Red or with "Steel" looking edge is more of a matter of taste than Lore and such,hell there are even specialtions about Dain's Armor being made of MIthril and such and although cool as an idea it is still an specilation so the choice about the Axe I personally leave in your capeable hands! I am more than sure thar you will not dissapoint your fans!
