Riverside Dog Walk Character Expansion

Using REFERENCE_0 as the character base, expand it into a full illustrated outdoor scene while keeping the same bold black outline, hand-painted texture, and recognizable character design. Change the character from a static standing pose into a walking pose, holding exactly 1 red leash in their right hand, with exactly 1 sweat drop on the face and a slightly tired expression. Add exactly 1 small dog, Shiba Inu, walking in front of the character on the leash, happy and energetic with its mouth open and curled tail. Place them in a sunny riverside path: blue river behind them, green trees along the banks, sandy ground with scattered dark stones, and a bright blue sky. Add exactly 1 white cartoon cloud in the upper left. Add exactly 1 white thought bubble in the upper right with exactly 2 small connector dots, containing vertical Japanese text あつい.... Keep the composition landscape-oriented, with the dog on the left and the character on the right, both facing left as if walking together. Maintain a chunky oil-paint/impasto surface texture, vivid colors, simple cartoon shapes, thick black borders, and no photorealism.
