I like what you've done here with #55. But the word "Brilliant" is hard enough to read with all of those pesky i's and L's in the middle as it is. A sideways word mark is probably not possible.
Can we focus on the Hat/Mustache you've produced there? The hat is cool and the eyes are unique. Could we try turning the Mustache sideways and working on making a B out of it with eyes/eyebrows or the hat or a hairline?
It's cool. But it needs some enhancing. Can you make the staches look more like letters? They will be clearly staches with the Hat there... which is a plus which would allow us to morph them to be more like letters.
