I like the orientation of your "knot" !
can you try one wihout the words (just the symbol) or with the words using the same font I did? (cafe lounge 19 -- all lowercase ...

also, could you do something to the top right cortner of the knot (that "D" shaped area) - whether it be tiling, thinner stripes, or anything like that - to make it a pronounced "D" ?
thank you!!!
