Live Portrait Sketching is an invaluable practice when painting portraits.
Tip #1: Keep your colour combinations simple. By limiting your palette, and paying close attention to your subject, you’re bound to have a greater level of success with mixing your colours.
Tip #2: Map out you composition. You have the opportunity to gauge how well your piece will fit the bigger canvas by sketching out your arrangement first.
Tip #3: Use a bigger brush. It’s vastly important to work quickly in a live sketch scenario, so speed things up with a bigger brush! This has the added benefit of forcing you into a more painterly technique.
