I tend to do two types of illustration - firstly those done exclusively in Photoshop, using simple shapes, textures and patterns, building up layers to make more complex images. This includes scanning in hand made collages. For these kind of images, I am influenced by illustration from the fifties and sixties - as can be seen by my Pinterest board.

The other kind is hand drawn, using pens as an outline, including a Japanese brush pen, then either using watercolour, pencils, pastels, or Photoshop to colour the images.

You can buy a range of my card designs and prints here:

However, if there is an illustration that you would like as a print that is not already on sale, then just drop me a line. Unframed, high quality giclee prints with archival quality inks on Somerset Velvet paper would cost around £20 for A4, £27 for A3.  For square prints, it would be £20 for 20x20cm prints, £27 for 30x30cm prints, plus post and packaging.
