First person, third person. narrator, omniscient or limited which one?

This is one of the biggest shell we say surprises I have had since I began to write fiction. For instance when I wrote the hundred and fourteenth word and that word being 'END' I was not aware of the amount of work that will go into this fictional journey. I have been over the manuscript at least four maybe five times each time thinking this will be the final time. Then I find myself picking it up a few weeks later and bang it's crap again.

Second and third draft, I would say spelling was an issue. Third draft was more more plot holes. Now I have started the next novel to this story, and I now find I have a problem with the way I wrote the point of view of the first book. I wrote first person in the first book, my narrator is third person. This I'm fine with, its the amount of each that is the problem. for instance in the first book I think I was more narrator and less first person. where in the second I'm edging the other way.

I suppose the question I'm asking is this ok considering these are different books or do I try and keep the same flow throughout all the books could this be my inexperience speaking? Could this be the show don't tell thing? but surly you have to tell sometimes.

I may need to go have a cup of tea and sort these out, it seems my mind maybe running away again, it's small grey and round, very wrinkled probable throbbing too, if you see it running down the road, please don't tread on it, I need it.
