Can I apply for a change of topic?

Are my sentences correct English?:

-Dear Teacher,

After looking through/viewing the presentation topics, I find that none of them is suitable for me; can I apply for a change of topic? I would like to present on a literary work/a reading as usual, in which case a student can talk about anything relevant as he wishes. Since the presentation accounts for only several percent/a small part/a small percentage of the final score, it would not be too much unfair to other students. But if you think it necessary, you can deduct some of the marks for giving me this privilege. Thank you. I look forward to your favourable reply.
