[Grammar] Do not be dramatic. It was an ingenious way to warn you to change your attitude

[Nikitus]

Hello.

Are the following sentences grammatically correct?

"Do not be dramatic. It was an ingenious way to warn you to change your attitude , which by the way is very bad."​

Thanks.

Yes, but there's an incorrect space in one of them. Can you find it?

 

[Nikitus]

The incorrect space is between attitude and which?

"Do not be dramatic. It was an ingenious way to warn you to change your attitude, which by the way is very bad."​

 

[GoesStation]

Yes.

It's not common to write do not instead of "don't", but it's not ungrammatical.

Was it an ingenious way? We don't have enough context to know suitable things are.
