Hi Ringo
Taking up on Stumpy's very sound advice, you do what you want to do and take your project as far as you want to take it.
A draughtsman colleague of mine some years ago when I watched him drawing a detailed plan gave me some good advice. When I asked him how he knew when the drawing was complete he answered 'Its complete when I decide its complete'.
This is the same with a painting or a book, its your project and you decide how to carry it on or when to end it.
What you don't want to do is get downhearted and give up your research or this site. Everyone that sits in here has a contribution to make and you are a valued member as much as anyone else here is.
So as we say over here don't be downhearted onward and upward.
Regards
Arthur
