Watercolor+acrylic quill attempt

I love the lineart already.
And no worries, my lines look pretty messy when you see them up close! Plus, it's kinda like when you look into a mirror and start to see excess fat and pimples where no one else sees it. d:

The acrylics I'm using are for airbrush, because of that they are very smooth. White ink works the same way, but has a nasty smell and will start to make globs of color only a short while after you got it.

Though I had to try about 5 - 7 different whites to find the one that was good for me. Never give up till you find it! Same goes for the quill tips. Those take a lot of tries too. ^^'

I tried Gelpens too, but like you said: They make ugly and far too broad lines.

As a tip for the current drawing: Go to a copy shop and let them make a copy of your drawing on two times the current size. If you can't get the white lines to be as thin as you want them to be, make the drawing bigger to make them seem smaller.

You can always make it smaller once you found the perfect equipment. That's what I did.
