There was alot of differences between using the oil pastles and the layers pro app. I personally liked using the oil pastles because i felt like i had more controll and it was easier for me to blend the colors together. The two ways of drawing values were similar because you could blend the colors together to add value. I was finally able to blend the colors on the app because the app allowed you to smear the colors together. The technology allows you to smear the colors without it being messy, and you can keep all your art in one place online.
