There are a lot to comment on in here. In general, I'm very drawn to the one of your wife(?) with her baby just next to the window. I think it needs a little more work, but I like the scene very much. I might crop a bit more and bright the light up a bit more so you can see the baby's face just a BIT better.
The boxes are a neat subject, but I don't think the shot quite worked. Brighten them up a bit may help. A different perspective (landscape) may have worked well here.
Overall you seen very drawn to portrait setups, but they don't always work for the shot... look at the prevailing lines in the image you are trying to capture and consider how those play well to either a landscape or portrait. If you're not certain, try both. #3, imo, really called for landscape.
The docks in #5 are slanted and unfortunately due to that bright sky most of the subject is too dark. Probably hard to avoid in that particular circumstance without washing out the sky a bit.
Big blue skies with cool cloud formations are great, but my recommendation would be to think of them as seasoning. They're not the main course, they just make the main course all that much better, and without them the dish may taste a bit flat. Don't take up too much of your image with them or you will be left with a big brick of seasoning and essentially no main course.
Just some thoughts... hope they help. I think you have a great eye and just need more practice.
