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
