¡Hola! Vivía in Barcelona en 2004 en Gracia para seis Medes. A mi me encanta Segrada Familia y Correfoc... Tan buenísimo.
I like your logo a lot! Can you please try to round the curls more to create more of a B and E shapes? I would also like to see it without the text "Brilliant Elixir" in the center (though I like your font choice so much).
Gracia it's a great neighborhood for living! At present Sagrada Familia interior is practically finished and it's awesome (Google images: "Sagrada Familia interior")
Now, it's a little late here but tomorrow early I send you some logo variation based in your comment.
