i'm wishing the lines were thicker...that's the only thing I"m having problems with it.

wow. it really looks like audrey. but i agree. the lines need to be more defined.

The lines aren't thick enough, and the umbrella seems weirdly pointless. Unless you're planning on drawing the entire umbrella I'd consider completely removing it. With those cut-off chunks of umbrella it looks more like you simply traced a photograph and slapped it on a t-shirt than that you created some sort of original design.

yea, toss the umbrellla, and the ear.... theres too much black there...

The chin is a little too butch to look like a woman... imho.

Sort of looks like Audrey with some Sophia Loren thrown in.
Take out the umbrella, finish the top of the head, and maybe move to the lower corner nearest to her shoulder. (Just my personal placement preference)

Thanks for the comments and advice. i'll try the changes and different colour shirts and post it up again sometime soon.
