How to draw a pixel painting?

The so-called pixel painting, as its name implies, is composed of pixels one after another, just like using mosaics to form patterns. Today, I will introduce how to draw a pixel painting in detail.

First, draw a pixel grid with lines on white paper.

Then count and draw the outline of the figure with a pencil.

Then fill the grid where the outline is located with a black marker.

Finally, color other squares with different colors, so that the pixel painting is completed.
