用字母绘制人物

背景

这一提示词测试仅经过文本训练的模型处理视觉概念的能力。任务较难，因此通过多轮迭代完成：用户先说明目标画面，再提出纠正、补充与反馈。后续指令应根据模型进展调整。这里要求生成 TiKZ 代码，用户需要自行编译。

提示词

第一轮提示词：

Produce TikZ code that draws a person composed from letters in the alphabet. The arms and torso can be the letter Y, the face can be the letter O (add some facial features) and the legs can be the legs of the letter H. Feel free to add other features.

第二轮提示词：

The torso is a bit too long, the arms are too short and it looks like the right arm is carrying the face instead of the face being right above the torso. Could you correct this please?

第三轮提示词：

Please add a shirt and pants.
