IMO they all look like you tried to match and you missed and honestly how can we advise on lighting when we have no clue as to your actual style which BTW from the pics of the space you should be going more contemporary. I looked at your idea books and if you were my client I would tell you to decide on a style before choosing lighting.

I have in the past bought something inexpensive that I didn't love so as to at least have something in place until I found something I liked. However, if you don't have DIY ability in your household, you will be paying for the privilege of changing fixtures later.

Your choices do not match the architecture of the space. If your overall style is more traditional than the picture indicates then maybe the fixture you selected wouldn't be a mistake, but it can be challenging to make a modern space traditional or visa versa.

To maybe help you get over this hump, I can say that it would probably be better to have the same fixture in both locations, but the other thing you can do is chose a different fixture from the same collection for one of them. Manufacturers frequently have many different types of fixtures in the same collection so they coordinate effortlessly. Maybe a semi-flush fixture in the loft area instead of a chandelier? A chandelier in the loft doesn't make sense on the surface, but I don't know what the space is going to be used for.

If you're not sure what your style is, look at pictures on Houzz and start compiling Ideabooks for each room with pictures you like. After you have 12-20 you should look for what they have in common and narrow down what you like to a particular style. As a non-professional it is easy to be all over the place, but your home will have a more cohesive look in the end if you can be consistent. In the absence of professional help you will have to educate yourself.

I appreciate the feedback.  I wish I could put a pin in on my style lol. 

I'll look for a more flush mount fixture. 

Traditional, Transitional, and French Country seem to always be in the mix lol.

Why not do as mentioned all from the same line but for different purposes they then can work together but still be different. Maybe a bit of bling

You really just made me laugh.  I'm going to check and see, lol.  This may be a case of what I see in the mirror is not my actual reflection but some warped version that my brain creates.

this is a case of cart before the horse, the furniture will dictate the style, and also the function of each room and the lighting needs, needs thought. I am not even sure what rooms we are talking about? what happens in the loft? What will the lower room be used as? Lastly that large room is going to swallow up that chandelier, not sure its the right scale for the space, I think you want this impact piece and you might be disappointed.
