I found the replication rather good, but Cosmo is right on this point: it's over-motorized. But I would not blame you for that, it's difficult to make a rocket both looking good and realistic. At least I suggest that you reduce the number of engines on your last stage, it's insanely powerful. Even my first stages generally don't have so much engines 
Well, unless I build a beast to carry several hundred tons to LEO.
Other point is the altitude at which you release the satellites: at that point they are in LEO. The Ariane 5 release its satellites on GTO (Geostationary Transfer Orbit). Ingame, it would correspond to an elliptic orbit which apoapsis is at 1800 km, and periapsis just above the atmosphere.
Then each satellite will circularize its orbit by its own means, while drag will progressively deorbit the empty stage.
Regarding the engines, Europe tends to use powerful boosters for the initial propulsion phase, and then to rely on very efficient cryogenic engines (but with low thrust) to handle the rest of the flight.
A single booster has a 600 tons thrust, while the Vulcain 2 engine (the one from the central core) generates only 135 tons. 90% of the thrust comes from the boosters at lift-off!
If you want to respect that ratio, you can use a Titan engine for each booster, and 2 Broadsword for the central core. Another possibility is to use 2 Titan per booster and a single Frontier for the central core.
As you see, it's difficult to respect both the number of engines, and their relative thrust
But that's still an interesting experience to build a rocket that matches those power ratio and try to fly it. If you try it, be warned that it's rather hard! In this case, your thrust/weight ratio should be around 1.5 if you want to have a chance (which is the real Ariane 5 one).

Western rockets are always using this setup, low thrust high efficiency core, high thrust low efficiency boosters.
1 frontier in the core is enough, TtTOtW and I already proved it works. Making the rocket as powerful as that in real life is ridiculous, since the game is scaled down a lot.

No, actually Ariane 5 can't do that because the last stage is not reignitable.
But that's how it's done usually, that allows to make reenter the last stage to prevent debris accumulation.
Moreover the satellites need some navigation capabilities, because they can drift slowly over time (because of slight imprecisions or gravitational perturbations). In general, the lifespan of a satellite is directly related to its fuel reserve. In the end they just use a part of their reserve to circularize their orbit.

Okay here's a suggestion: try to put a docking port or structural parts to maintain both halves together and hold the upper satellite, which gives you something like that:
