Are the expressions above grammatical?

If there are inappropriate expressions, would you correct them?

Draw a tie around the neck or on the chest?

#1. Put a semi-colon after "so". Those are two complete sentences; so they need to be joined by a semi-colon, not a comma.

Yes, a tie goes around the neck, not on the chest.

Sorry about that John, I meant BEFORE "so" , not after...opppssss.

Based on the given sentences, there are a few grammatical errors that need to be corrected. Here are the corrected versions:

1. In the picture, there is no hat on the person's head, so you should draw a hat on the head according to the dialogue.

2. You should draw a tie on his chest.

3. You should draw glasses on the dog's face.

Regarding your question about drawing a tie, it is more commonly understood to draw a tie around the neck rather than on the chest. However, the specific instructions given in sentence 2 suggest drawing the tie on the chest. So, in this case, it would be appropriate to draw the tie on the chest.
