I've tried out Daniel Sanders Intense Volume Pro Mascara, and LOVE it! The brush is flat and narrow on one side and round and wide on the other, so this mascara will do anything you want a mascara to do. It separates the lashes, as well as it gives them great volume and length. The color is a very intense black that will make your lashes look thicker. After wearing it all day it hasn't flaked or smudged at all, even though it's not waterproofed it stays through a lot. The mascara is £18.50 and you could buy it here --> goo.gl/7nRCFP
Here's my eye without mascara, then one coat on and the last picture with two coats.
