Here goes constructive criticism.... brutally honest. Visual it looks great. Nice polished frames, nice rendering.
But you missed the mark on the basis of the story. This could have been the next big installment to visual novels, if you had just done the research. A person who has been in a coma for over a year would have no motor functions and severe muscle atrophy
which would lead this up to endless possibilities. It could have lead it to a funny comedy where the MC's sense of humor excepted his memory loss and just started doing perverse shit, because someone would have had to take care of him such as
helping him shower, and dress, get him to bed,
or going to the bathroom even. Close human contact would be essential in his case. What? her clothes got rip off exposing Full Frontal because he has no coordination or control. Stupid coma! It's not your fault. No one could get mad at you!!!! ever!!!!
If you wanted it to be a serious story that could have worked also. Close contact, emotional bonding, the invalid nursed back to health story.
But instead the same cliche soap opera
lather rinse, repeat, or more like hand job,
foot job, blow job processes that follow the same pattern of with way to much dialogue regerjatating the same thing over again kind of stories already out.
I most have missed the part when the MC wakes up from a coma, because when he gets home the two other characters start bitching about being depressed or have to take out a second mortgage. Nice way to make somebody who just woke up from a year long siesta feel like shit!
I'm not trying to be harsh, but the overall basis and potential on what the story originated from could have pushed it in any direction. If there is a way to back track on the story and implement the invalid bit this would become a " source " of motivation.
