Submitted Assignment Late - Wrong to ask for in-depth analysis?
You submitted late and did half-baked job. It does happen to the best of us.

It does not, however, make sense to expect the lecturer to invest on a piece of work that you yourself consider subpar. Any information that they could give you would probably concentrate on the things you anyway know are problematic in this submission. If you did your best job, detailed feedback from the lecturer is valuable in refining your work. 

But if you didn't, and you know it anyway, you would just utilize their time/attention to little effect and would take it away from students who did - in this particular instance - a better attempt.
