hehe so many people learning this now
^_^
i hope it doesn't become over whored
but anyways back to your piece
nice job for your 1st time
just idk work on spacing and size
i personally think its to big of a px brush (that goes for both the main (large line) and the sub-shadow (smaller line))
keep working on that
also
you don't have to use so much
sometimes things are best in small amounts
but keep working on it man
and good luck
