Well, there's a lot to like about these, your use of lighting and lines especially. When you try this on Monday with the bike maybe play with the glass and show the bike in a reflection instead of having it directly in each photo. But how can you demonstrate all three disciplines in one photo? Cycling is easy to show, but it's harder to separate and show both running and swimming when she's not actively doing either thing. Maybe you can incorporate her footwear in a single photo: barefoot, bike shoes and running shoes.
