Someone take a look at my art?

Hey everyone, i'm a 22 year old female who has been looking very seriously into approaching a shop for a tattoo apprenticeship, I have been doing my homework and building my portfolio for a while now. I was just wondering if someone could take a look at my art work and give me any tips or critiques, I need some feedback from someone outside my social circle and who understand tattooing and are respected artists. I really appreciate any helpful feedback, don't be afraid to tell me the truth about my work! Thanks! http://www.facebook.com/media/set/?set=a.1026471186253.2004599.1359490377&type=3
