Here are some really bad pinup girls, for your viewing pleasure.
Please note that they are all A) badly drawn and/or B) badly executed.
Look at the proportions on this one! She has no neck!
This is obviously a photo of a fresh tattoo, so I'm sure it evened out and looked better once it healed. However, the shading still looks splotchy, the 'halo' around her is bizarre, the mouth is wonky, and the outlines look scratchy.
The linework on this poor girl is terrible, and the drawing is too.
