Research into potential target audience: Feedback on filter effect

Using the social media site snapchat i decided to ask my target audience what they thought of the black and white filter that i added to one of the scenes in my trailer.
The feedback was as followed:

As you can see from the feedback the target audience very much liked the idea of having the scenes filtered in black and white which made me relieved as it meant my thoughts were paying off and were actually liked.
Some of the comments stated aspects that i thought such as "mysterious" and it being "unique and standing out" while others said that it went with the genre and that "it puts emphasis on the storyline".
So overall i am very happy with the comments received from my target audience as it means that what i have done is good and is also effective.
