Film/Video - Remember when filming that it's not all about having the best camera. Lighting is so important and it can turn a "Student" film into a proffesional one. Think about your lighting.
Art - Go out into the real world and draw something. Maybe there's something in your garden that you would like to draw.
Music - When making music, please remember that the way you play notes is so important to creating effects. "Rhythm" is a great thing to focus on. Try experimenting with different rhythms today.
