mercury ripple

yup, another one. a bit different this time thoguh. the first two ripples i made looked the best but the screen looked too empty with just them (they are theones just to the outside of the ring).
a whack of people saw me last one but noone commented at all.
SO COMMENT! i need to know what everone thinks. what can i do to make it better? what am i doing good? tell me! i need feedback ><

comment!
