Beige loafer shoe Refashion

I have always admired bloggers who are brave enough to dye their shoes or add all sorts of embellishments on them. Since I'm new to shoe refashioning, I thought I would just try a very simple one for now.

I thrifted these almost new beige loafers for a great price. They are very comfortable but just really boring looking:

I also thrifted these medallions from the thrift store. They are quite heavy and seemed to have been components of a bracelet but someone has taken them apart already:

I just glued them onto the loafers with 'No More Nails' adhesive. I hope they will stay because the medallions are heavy and they can be flung off if I run in these shoes.

My first shoe refashion! Yay! So, what do you think? Is the embellishment too ornate for such a casual shoe?
