Storm Shield basic model

Since I think that the plastic storm shields from the Terminator sprue are way too small, I am constantly searching for a nice alternative. Therefore it always annoyed me to see that these super awesome Forgeworld storm shields are only available for Black Templars, or rather that it simply would be too time-consuming to remove all the BT insignia.
So in the course of 3D-modelling I always wanted to make some strom shields that look similar to the Forgeworld shields. Today I made the basic model! I didn't model the handle with the closed hand, because it's too complex. I'm going to make a silicone mold to cast the handle from the original shields and glue them on later.

Not quite sure what things I should model on it's surface for the Terminator squads, but I've got quite some nice ideas for the Captain of the Battle Company.
