Writing is quite good! It would be nice to have a bit more lewd content at this stage. The few scenes that exist are kind of rushed and feel a bit detached so the hot-meter never reaches very high.
If I could make one note. For it having a film noire/PI theme, it never really feels like the stakes are very high. Even when our MC get into fights, conflicts and the like the mood just stays kinda lighthearted and comedic. You would expect a bit more of a sense of tension in this kind of story. Making those darker elements a bit more serious would give us a break from the comedy that would help us appreciate that comedy more.
