The Sanguinary Priest was first offered as a metal blister, and that is what is being reviewed here. It has since been moved to a resin cast model, so keep that in mind.
Here are the pictures GW offer to sell you the model.
The Sanguinary Priest is definitely in a dynamic pose. However, it does not really show just how far forward the model is leaning. It also hides the very bland top of the right hand with the narthecium. Having a bolt pistol is a little generic too. The solution is to grab a nice chainsword from the Death Company kit to make it appear the Priest is in close combat. The double bonus is that you then have a nice stand in model for Corbulo without having to buy him and his cup. Corbulo's chainsword appears to be fairly non-descript anyway on his model and not a particularly efficient purchase unless you have a particular affinity or compulsion to be a completist.
