ok I am trying to remember my subliminal advert course...I would
Angle the wedge of the lemon in the glass (3 ice cubes also angled and clumped sorta)
Change the Font to match the coffee cup font its cleaner and I would make the background solid black behind the table,the lettering white and the coffee cup words a shade of dark green its hard to look and not do so it may look like shit..I usually just play around.. or not
lose the arrow the color will draw the eye
good luck with it love to see what you end up with
