Shield Designs for Logo

The second lot of designs I did shields within the medieval period, as this was the closes to get to sort of shields that would have been used.

Here's some of the designs I have sketched, using the research on the internet that I think would look the best:

I have only sketched five designs of these shields, but I have two favourite shields the top two on the right side, where the are seminal and best for one of the logo concepts I have been thinking of for that logo.

With the colours of the shields would follow the a sort of medieval look to them, using different tones silver and/or black either as the main part of the shields or as the lining to add the darker look to it.
