It's wonderful to hear about your passion for wildlife painting and your connection to the expressions of the subjects. The smaller canvas size of 20" x 24" can often enhance the impact of the details, making the painting an intimate and rich experience for the viewer. Wildlife art often captures the essence and character of the subject, and your focus on facial expressions adds a personal touch to the portrayal. Keep exploring and sharing your love for wildlife through your art—it's a meaningful way to connect with both nature and those who appreciate your talent.
