Pen and Ink app plus Spray Can app, sketching on the ipad
Quick sketch from life, the window sill and silhouetted resident tiger
And yes the plant is tipped over thanks to madame there, my perspective wasn't out! Done using the Pen and Ink app, then opening the image in the Spray Can app. The trouble with this is that it sprays over your drawing, whereas using Photoshop on the computer allows you to work in a layer beneath. I used a low opacity so that I could overlay colours - there is a very limited range.
I haven't used the spray app much yet other than this.
