With digital art, you don't really have to be afraid of "messing up" a good-looking drawing, since you'll always have the undo button
If you're going to use this piece for lineart practice, then I'd recommend test out the "Flip Horizontally" button at the top of the drawing area in Sai. Artists often unintentionally slant their art in the direction of their dominant hand, and it's easier to see/correct it by flipping the entire image horizontally while inking
