tamlin is right..no magic or trick to do clean vector like that,even live trace tools cannot do it..its human touch..just take 2 or 3 can of soda drink from your icebox..relax your mind and select pen tool and start tracing..if you feel tired or bored..drink your soda and double click your window media player thumbnails and play some relaxing music....and when you feel lost .. come to biorust..find some tutor or ask people around you..they're very friendly...
