I love your cell shading, wish I was that good with it, but no such luck. Your sis seems like a very pretty lady. I love the colors on this peice and the anatomy looks flawless.
P.S: If you found my comment helpful perhaps you'll spare a few seconds to help me out? I've just started designing clothes and entered a fashion competition. I am very close to winning; I just need a few more votes on one of my sketches. So, I ask you, pllllleaseee, if you happen to like my latest fashion design, might you vote for it? Only thing is, that it's not on Deviantart, but on a site called Garmz, so you have to create an account there, but it's really quick, easy and free. You don't even have to provide your real email address or name. So, what do you say? Here is the link to my design: [link]
