i like u smudging
u hsould improve on depth and lightning
the motion blur on the first on, dontuse on light sourc, it ruins it.
try using decent and dull colored text on dulled smudging, in fact its not necessary to write text
although almost no one here is perfect with text
though try papa's text tutorial here on void.
i like the third one though its good an different, if u remove the huge vector brushes and get in smthing smaller, it would be gorgeous

GJ Welcome to Void and keep up the good work, hope you enjoy your stay here
