The BMW Series is a bit akward because of the too pronounced shadow effect on the borders (we call that the “vignette” in french, dunno how to translate into english). However, your framings are good but you should take more risks : most of your pictures are close-ups. So try to find more innovative views and get your own settings, balancing between exposition, luminosity, aperture, etc… Good luck
^ I see improvement already! A big thing you’re gonna need for progressing from everyday joe to fotographer, is aperture. It will definitely make your shots stand out more. You don’t have to overkill it, but a subtle 40-70% should be enough on most zooms.
