Rotate cube a bit and draw one of sides of cube with lighter grey than another.
You dithered too much so cube and letters are hard to read (don't dither - and it will stand out on dithered background). Also letter 'K' looks unfinished (vertical 'holes' are too short). Exclamation mark is 3 times thinner than the rest of letters (it should be as wide as "I" part of 'B').
And for proper avatar better substance needed - see how graffiti writers add stars, bubbles and characters to their pieces.
