Guitar Art Festival in Belgrade is an event focused on acoustic guitar performances, and more specifically - ballads. I went for a classy look using a stylized serif font, and tried to keep all the elements to a bare minimum. 

The main element is the guitar created out of the acronym "GAF" (Guitar Art Festival). I added a few more details like a border and almost-invisible letters in order to discreetly make the design feel more complete, without distracting from the main event.
