u know
i used to do my sketches the same way
the problem is if we wanna make them good the ends are always bad but if wanna make it smooth its always a bad sketch
an easy way is put it on photoshop
make 2 layers 1 with this pic
use the other layer to trace down the pic(this time with nice ends) and delete the 1st layer it'll look like real anime kakashi
i do the same but i never show it to others (got plenty of dbz images)
