For the new professions I chose armorsmith, and even though I did not start crafting items, I did look at what they might look like through preview. However, all of the shields, from Bronze through Mithral, do not appear on the preview. The armor sets do, but shields do not. I do not know if that is a Dragonborn bug, or a bug across multiple races.
It would also be a disappoinment, if one crafted one of these items for a transmute look, and it showed nothing.
