I like the colouring on 54 very much, and also love the font! Im not too sure about the shape coming off the side. Im thinking in terms of centering on say the top of an email or a letter head! If you could make the shape more central, so that the logo looks nice and neat within straight lines, maybe put it at the top of a word doc with some text so you can see how it looks?
Thank you for the great entry!!
