The M/M yiff is not a direct hook for me. The vore is, so some scenes i was like:
-"does this lead to vore? no and that scene was not for me." "Does this lead to vore?...no but that was kind of cute"-
your story telling seems very good so far and I will check the new project to see how your longer story telling goes.
Also, with a little imagination, some of the images of both stories kind of already have a micro pov. if you were going that big of a size difference.
Hope you had good holiday and remember not to burn yourself out learning the new engine.
