1. SUGGEST DETAIL
Instead of putting in every detail try using bigger blocks of color with just a few details. The viewers mind will fill in more detail than the eye can see.
2. THINK BIG
Even on a small support you can still suggest scale and depth with aerial and linear perspective. Remember to layer objects and have less detail, cooler and lighter color and less contrast in the distance. This will help a small painting seem more expansive.
3. USE ‘BIGGER BRUSHES’
To create a looser more expressive painting and to hep you keep things simple use the ‘bigger brush’ approach. Don’t rely on pointed hard pastels of pastel pencils as they may cause you to become too concerned with details. Use your large pastels and you will make bigger marks. You can actually get detail with the edges of a big pastel but you are more likely to be more expressive.
THINK IN THREES
To simplify your subject to fit into a small format think in Threes. When planning your painting allow yourself to choose:
THREE SIMPLE SHAPES
THREE VALUES....dark, medium and light
SIMPLE LIMITED PALETTE with other mediums you would only use three tubes of paint and mix all of your colors. In pastel you should keep your palette limited to 12-20 pastel sticks.
THREE FINISHING MARKS after blocking in your big shapes and developing the painting to a finish, allow yourself to make three finishing marks. These will be your final details. Choose their location carefully.
