here is someone who seems to be selling a lot of work and the lettering is super naive. it looks like she just started copying things and was not too concerned about seriously studying the traditional styles. there are raging debates among lettering artists about whether this debases traditional calligraphy. i always compare it to the Gees Bend quilts. those ladies just did whatever pleased their eyes and the happiness of the process shines through.
karli's art is very happy and might inspire you to just make letters, be happy, and don't stress.
