I am a masters student, and am currently writing an expository article on an area of applied maths for a class project. I plan to work on it for several more months. One of my major goals is to improve my expository writing skills, and I thought one way to achieve this might be to try and submit this article to a journal for peer review. The topic is also of significant interest in several fields.
I have checked and Bulletin of the AMS and Notices of the AMS have both published work similar in flavor to what I have in mind. However, all of the articles I have read from these journals so far were authored by senior professors. I'm not sure if this because articles from established experts are preferred, or if it's because more junior people may have an incentive to focus on their original research rather than expository writing. Would it be pointless to submit as a student? If so, are there other venues that could be reasonable?
