Painting In Photoshop

Today we were looking at creating images in Photoshop to look like still life paintings. We were to draw a basic image of an object, in my case a simple cup. Once we scanned the image in and put it on our computer, we opened it in Photoshop. If need be, we could alter the curves or levels to brighten the image or darken the lines. Next, we changed the brushes to Dry Media Brushes and altered the brush's opacity. Then, using the Magic Wand tool we selected the area's of the image we wished to colour. Then it was just a case of layering on the colour the same way you'd layer on paint.
Here's my finished result.
