The convention here is to use the CB to ask questions such as the one you've just posted (ie, don't use a SOPW to ask whether to post)
OR
just post a SOPW, with the code (inside code tags) and narrative notes (in para tags) asking about specific areas that make you wonder if the code is well written. If there are no snippets/segments/constructs about which you have doubts, a generic "How can I improve this?" can do little worse than fail to draw comments (unless it's so badly written that you draw downvotes for your exposition/formatting).
