The two fixtures don't have to be similar but should be the same finish. You could also augment the light in both areas with recessed cans in the Foyer and possible some wall sconces in the Dining Room.

I agree that they don't have to be the same, but should coordinate. In fact, I would probably make them different. My guess is that your existing fixtures may have been installed by the builder, and they just put in the similar fixtures because they bought a lot of them from that line.

Of course a lot depends on budget. I would go with a semi-flush mount drum shaped light in the entry. That way it could bounce light up and down, depending on drum, and give you more light during the dark winter. Drums could be closed with cloth around the edge, but they could also be open.

In our 1969 home, we have a Feiss Colorado Springs 3-light flush mount in our low ceiling entry. I love it, but my wife doesn't like this flush mount as much because the bulbs show. However, a semi flush mount would work for you since you have a higher ceiling:

The Feiss semi-fulsh mount is very expensive - I just show it as an example of a style. There are many less expensive, but very nice looking lights that are similar. Start filtering here:

Look at your space, detemine good physical dimensions, how much light you need (lumens) narrow down some finishes, then explore. Change to a different shape if you don't like the drum.

Most standard lights can accomodate LED bulbs, which come in a wide variety of color temperatures and lumens. You might need to upgrade a dimmer switch for LED.

Do a similar thing for the dining room. However, that can wait. You could do the entry first, live with it for awhile, then tackle the dining room. As long as you stick to lights that can mount on the same junction box (and aren't too heavy), it is pretty easy for the homeowner to DIY this replacement.

Dining room can be very similar to your existing fixture if you just want mood lighting for dinner. However, if you do other things, like play games, do homework, etc, then you might want to consider something with more down lighting than your current chandelier. This follows from Michael's comment also - you might want more or different light in there. But adding in more fixtures goes beyond capabilities of most homeowners, though (electrical codes, permits, wiring, potential drywall repair, etc). Changing out the chandelier with something that gives off different types of light can give you more bang for the buck.
