This looks like a great work in progress. I say 'work in progress' because there are a lot of little things
that you could fix to make it better. Its not one of those projects that have fatal flaws where no matter what you do,
you can't make it right. I know because I've had plenty of failed projects. If you don't mind my saying,
I'd like to point out a few things that you could easily fix.
1. Make sure all your fills actually fill in the space between the outlines. There are a lot of spots where the fill
color just doesnt go far enough and you have these white\light spots right next to the outline.
2. If the vector is supposed to be a single, continuous curve, always use nodes that have handles on both sides. If you mix the two you get awkward looking curves like the top part of her
tattoo. That top oval shouldn't have a pointed peak in it at the bottom of the oval.
3. If you absolutely cant just use one line, don't just connect the two vector lines. Overlap them by 3 or more
pixels so that the transition is smooth.
Those are just a few suggestions that work for me. I hope that I didn't come off sounding like a know it all. Thanks for sharing your work.
