Observe the different shades of green present in the lemon's flesh, ranging from light yellow-green to deep forest green. Carefully select the appropriate shades and use your brush to apply them to each segment of the flesh. Pay attention to the subtle variations in color and shading, as they will add depth and realism to your painting. Remember to leave some areas unpainted to allow the white of the paper to shine through, creating a subtle highlight effect.

Using a variety of yellow and green hues, carefully apply small dots and strokes to the lemon's surface. Experiment with different shades and patterns to create a truly unique and captivating appearance. Remember to vary the size and density of the dots to create a sense of depth and texture.

Let's give our lemon some depth and texture! Grab your brushes and some darker shades of green and yellow, and let's get creative. Use these shades to create shadows and highlights on the lemon's surface, making it look more realistic and three-dimensional.
