A vintage-style hand-drawn illustration featuring a contemplative frog sitting in a relaxed, meditative pose with legs crossed and one hand resting on its chin in a thinking position. The text 'Sometimes I Just Be Thinkin'' is arranged in a chunky, bold serif font with gentle curves, colored in muted sage green. The frog is rendered in the same detailed crosshatch and stipple shading technique with textured line work creating depth and dimension. A small thought bubble floats near the frog's head. The character maintains the same vintage natural history illustration aesthetic with careful attention to anatomical details like webbed feet, bulging eyes, and textured skin. The design uses a single earthy green color palette matching the original's muted sage tone. The composition is centered and balanced with the text stacked above the illustration. The design is print-ready, fully isolated on a white background with no shadows or textures, fully contained within canvas boundaries with no cut-off elements and proper margins around all elements, and intended for use in t-shirt printing. | PODspy AI Design
