We never worked together in your "earlier period" so my thoughts are based on your profile now without any history attached.
I can see why you suit the "vintage" look - stick you in a 40s style dress and plonk you next to a steam train and it would "just work" 🙂 but it probably works because you have a very natural look that could adapt to lots of different things. You've got some variety there already:
The red dress in the car shows a classy, sophisticated look (although the photo itself has some technical issues with focus and exposure - I won't give unsolicited critique, perhaps something similar but stronger can be found?)
The peach sheer top combined with the make-up and coloured hair shows your strengths for fashion style images and looks great.
The green swimsuit in the "desert" has a great cinematic feel, especially with the way your hair is messy and blowing around - this is one of my favourites.
The one I like the most is the current cover-image - no nonsense, shows your natural beauty, with a pose that looks relaxed yet professional. If you were a film or tv actress, it's the kind of thing you'd have on your profile for casting people to see.
Anyway, I don't know if that's helpful or not, just a few things that came to mind. You can also ignore everything I said as I'm certainly no expert!
