[milo]

apparently you can have half a foot missing if you end on a feminine syllable (though don't take my word for it)
however, you have a half foot too much which i'm pretty sure is a half foot to many. that you call it a transgression implies you didn't mean to do it, if that's the case then change it, if you did mean to to do it, then question is begged; "why"

halffoot extra always occurs with a feminine ending in iambic, there is no other way to do it so it is not really a deviation at all.

half foot short occurs with headless iamb. This should be used sparingly as your predominant meter easily slides right over trochaic.
