The ears and mouth were not well painted, and there was no careful observation and study before painting.
Sketch one. Record it
Complete diagram. This one feels a little better. Except for the chin that is slightly longer.
The seats behind the tricycle are painted larger, and it looks like the perspective is different from what is photographed.
Sketch one. The starting part felt OK.
Sketch two. Is the chin a little shrunk to the right, or is it the reason for the right tilt?
Complete the diagram. Thankfully, it's not too obvious.
The front part of the trolley is not drawn correctly.
Copy a dynamic sketch behind it. I feel that this kind of small picture is really not easy to draw, especially the details, that is really the kung fu.
This piece of mouth and chin is the most modified. I usually don't bother to modify it, unless it looks too bad.
After this, I am still not satisfied.
One of the troubles of pencil drawing is that you need to cut the pen head long and sharpen to be easy to use, which can produce a good effect. Sometimes I am too lazy to sharpen the pencil, and I can obviously feel that the drawing is difficult and does not produce a good effect.
As the saying goes, if a worker wants to do good, he must first use it.
Therefore, if the drawing tools are not prepared in advance, how can they draw good drawings?
