Today I felt like using a completely different techinque! I've been using the pen tool in Illustrator 

instead of the usual brush tool in photoshop. I think I do prefer this tool, the lines are crisper and the image in itself is more accurate. Anyway, I found this picture of a peeled banana and traced it using the pen tool.

After this, I filled the shape in with yellow to create a bold, simple shape that I thought looked very effective.

I then created these two images, the left image I added a little more colour to define and add detail to the image, and used a coloured background, much like a Julian Opie piece. On the right I worked more in the style of Michael Craig Martin, as it's bolder, but using darker colours. I really like how they have turned out!
