Class (classroom) management tips?

Yes, I have looked up and found two questions that are relevant (Q. one and Q. two. I find the tips good.

I have been little more kind towards students. I haven’t reprimanded anyone. So, what it is turning to is students keep on talking in the classroom. Secondly, quality of the assignments (more specifically drawings on sheets) is deteriorating. Do I turn strict on students?

And, few (sincere) students have asked me to be strict since they find others’ talking disturbing.

My fear is, if I turn strict, it will be too hard for students. What should I do? What do I say? any examples?

What are your suggestions? tips? advice? Your response is appreciated in advance.
