This is a really simple way to create daisies with a dotting tool.
Paint a base colour on top of your base coat. I went for a sky blue, but any light pastel green, blue or lilac would look great.
Dot on the yellow centres of the daisies. I used a fairly large sized dotting tool for this. I went for 2-3 daisies on each nail, but you could use a smaller centre dot and add more daisies onto one nail.
Use a smaller dotting tool and add the white petals, they should be equally spaced around the centre of the daisy.
Add some randomly spaced white dots to fill out the design a little and your done!
