shunkan ja ikura Nakai-san demo konna kaki-kata muri daro...... 週刊じゃいくら中井さんでもこんな書き方無理だろ･･････

Impossible.
Unreasonable. Unmanageable. That can't be done or that won't work.
The character is saying that, despite Nakai's abilities, it'd be impossible to draw using stippling in a weekly serialization, since he would have to render dozens of pages every week using this technique and there just isn't enough time.

The drawing is extremely pretty, isn't it.
