Striking Isometric Design

Create a striking isometric design that spells out the word 'SKETCH' by arranging artist's paintbrushes with bristles that gradually taper at the ends. The brushes should feature a soft, warm pastel color scheme, harmonizing against a serene mint-green backdrop. Employ delicate, natural lighting to highlight the texture and detail of the brushes, using a high-quality rendering technique to achieve a realistic appearance. Place the composition centrally within the frame, resulting in a contemporary and visually captivating piece.
