I for one love branding, so i'm a little biased!
However, I like the mixture! I would maybe make it more cohesive for your shop layout though, so one line of photos with the brooch on an item of clothing, and one line of brooches on your cards if that makes sense? Then you're pleasing both markets.
Also, might be worth keeping an eye on which items get the views, if you get more with your branding or not, then you know which direction may be best!
