Just my two cents on what a limited edition standard might look like.
One of the most popular standards that are sought after is here
http://www.coolminiornot.com/280617 Kordel Shogar... its from another game system but beer with me...
The banner is big and exaggerated, something there really isn't currenlty for dwarves, they are all static eblems and runes... no real chance to display custom banners.... it has chaos icons on the top, but how easy would it be to replace them with dwarf icongraphy.
The model itself is armoured to the nines, including a face gaurd on his helm, and a fured cloak.... the facegaurd is again something seldom seen on a model, especially when its open... just looks awesome in my opinion.
The model has a weapon behind his shield... also very cool, not often seen in dwarf models...
What missing... a pipe or pint..... could do lots of things, a large runic hammer on his back instead of behind his shield.... but the banner and the helm are musts, they just are unique to dwarves....
