From the review I've just looked at, it appears as though it does support it. Also the review says that if you have the free version, you can try the pro features for 1 hour for free,
"Tayasui Sketches looks simple and clean, but it offers a number of different brushes for free and a clutter-free space to draw. You get a pencil, rotring, watercolor brush, felt pen, and eraser for free. You can import photos, too, if you want, and it’s really easy to share your sketches on social networks or via email.
It’s great for illustration and quick sketches, but if you buy the in-app purchase, it can become a professional drawing app with surface pressure, layers, types of paper, more brushes, and the ability to change brush sizes. The app lets you try the pro features for an hour, so you can decide if it’s worth the $5 price tag. Regardless of whether you pay for pro, you can organize your sketches and creations into different notebooks in the app, which makes it easier to keep track of everything. Thanks to the backup feature, you won’t have to worry about losing your work, either"
I hope that this helps
