It's when I start to put it down on paper that the problems arise. I admire those illustrators that seem to see a perfectly formed idea in their head and then simply make it real. My process is slightly more evolutionary with tweaks and subtle changes happening around the basic concept.
Some ideas stay as initial pencil sketches for a while (dependent on deadlines) and I can work/rework these adding a little more detail at a time.
Before starting any project I always find it helps to do at least a fifteen minute 'warm up' sketch. A bottle of wildflowers sat on my desk did the trick this time.
Back to the project at hand. No need to zoom into the detail yet as my first layer is just roughing out basic colours and tone. Using a wacom tablet and stylus (digital drawing tablet) combined with the drawing and painting tools of Sketchbook means that this process continues to feel like traditional artwork. The only significant difference for me is that I'm drawing on a tablet on my desk and watching the results on my monitor. The hand to eye co-ordination issue takes a while but once you get the hang of it then it becomes almost second nature. Initially working on a Quantel Paintbox back in the late 90's on breakfast TV provided a great and steep learning curve.
