I love illustration work that is hand drawn, sketchy & feels 'underworked' like Debbie Powell's. The illustration for the Jamie Oliver's tea packaging is just fantastic. Here are a few snapshots of her work... more can be found here.
It is too often these days that you see designed and illustrations that have been whipped up in a flash with little or no attention to crafting and detail. However, this can not be said of Si Scott. His incredible unique mind bending illustrations leave me wondering how on earth he even he even began to start them.
