Here is some fun still life artwork and even a portrait of my dog, Sara that  I painted on my Ipad using the Art Studio app. This program works similar to Photoshop as it has many art tools and Layers (yes, layers!). It only allows for five layers maximum, so you have to be somewhat strategic in planning your painting. I find my self creating my background on the bottom layer and putting other elements on the middle layers and save the top layers for shadows and highlights. If you have an Ipad, I highly recommend trying this app for yourself.
