The Little Mermaid
When I was approached by Adobe to create an image using the Adobe Photoshop Sketch app, I jumped at the opportunity to play with new software.  I stole my girlfriend's iPad, borrowed a Jot Pro stylus and started mucking about.
Loading up the app, I first laid in a sketch and started to paint.
By placing the sketch in as a separate image, I was able to turn it on and off like a layer as I worked.
I wanted to create some custom brushes to use on the image.  Using the Adobe Brush app, I captured and imported some doodles I drew on paper.
After importing the brushes in Sketch, I was able to easily use to to add textures and lines.
With the image completed.  I exported it to Photoshop where I did some tweaks and adjustments to the colours and contrast.
