My first puzzle joint looks about like that. I am working on hatch supports now and my skill, while not mad skills, are definitely better. Like Stevie says, your subsequent work will improve vastly! I hate the look of that joint every time I look at it but I know it will be covered by headliner so I try to ignore it.
Eric had a suggestions about rolling up wetted tape before laying into place. I responded to it today so it should come up in a recent response list. I strongly advise that method! It is not as messy as it would seem.
