No. A conclusion is a summary of YOUR ideas and your opinion. Task 1 is simply reporting what you see, so there shouldn't be any of your ideas or your opinion.
Instead of a conclusion, you should write an overview.
The reason lots of people get confused about this is that some teachers, books and even one British Council website call the overview a 'conclusion'. It's not a conclusion, it's an overview.
Finally, it does not matter where you put the overview paragraph. We teach our students to put it after the introduction, but it is also fine to have it as your final paragraph.
