Alfa looks a little to clip art I would refine it
Bravo I like it, maybe throw a sapphire in there tho. Like on his hat buckle or something
Charlie Why a leprechaun? Sapphires and leprechauns and sapphires are not necessarily related. Good. Now, what if you substituted a sapphire blue for green?
Delta Maybe something more simplified, or instead of the leprechaun a sapphire integrated with something else pub related, and give it an aged look, love the font choice though, keep that :)
