I watched the You Tube tutorial yesterday, and thought I would have a go. I have a Samsung tablet, so downloaded a different free app, called Smart Paint, but it is very similar. I tried a landscape like on the demonstration, but have only used an ordinary stylus or finger as yet (bidding for a brush, as Rockgran recommended, on Ebay, currently at £3, ending in 20 hours.). My picture was rubbish, but I started to get the hang of the painting and blending techniques. Wish me luck. I am not in the least artistic, so I don't expect to be posting the results!
