She means penis-y.
Don't mind her. She picks her nose and sees phallic images everywhere.
It's a nice image, but I think the shading is way off here. The fabric folds into waves, and there should be shadows in the "valleys" between each wave, while the top of each wave should be white. Also, the head has shade on the top right side, but a lot of the folds / waves on the fabric have shade on their left side. In other words, you've shaded the "skirt" almost opposite of what it should be. :)
My english is not the best =S, what do you mean by "phallic" ?
BR: Essa ramp foi ruim demais, as cores não se igualam muito bem para um bom dithering. Podia fazer ele menorzinho porque é dificil trabalhar obras grandes. Poderia também ser as duas partes iguais, e esse olho foi fail.
EN:This ramp was too bad, the colors do not match very well for a good dithering. Little one could do it because it is difficult to work works great. It could also be the two equal parts, and this eye was fail
Based on the reference you provided, I'm fairly certain the bottom set of waves are supposed to be the back of the sheet, so the feet in your picture need to be between the top and bottom sets of folds, not behind both of them.
