I love Carl Jung.
I've seen a few errors crop up among beginning writers (like myself). These include:
Over-explaining (wordy) or redundant words, clauses, passages
Filter words from the point of view character
Drifting in and out of point of view.
There are others, like telling more than showing, and abusing certain words and word types, and relying too heavily on the sense of sight without drawing in other senses, but I thought I'd give you those things that I see in critique circles as food for thought. They are all discussed on blogs and are google-able.
I have no idea if any apply to you - but I feel like we're at a similar stage in our fiction journeys. These things have been blind spots for me and seem not uncommon.
