Always interesting to look at designs others produce, remember we are talking about a design that probably had lots of competition, so it probably does a few things right and it never hurts to look at solutions other people came up with for various problems.
They might use a clever datalink system that is more efficient or lighter and longer ranged than the ones you currently use, or the camera might be better stabilised or use particularly good stabilisation software or whatever... or you might find there is space for a HE charge if you want to fit it... which would be useful information to those having to face it not to just let it fly towards them for example.
It might not be of any value at all, but just seeing some alternative choices or similar choices they made in the design is always useful for any designer.
When starting to design something you always analyse existing solutions to see how they solved the various problems... it is not a question of copying as such, but just like with the Soviet Buran and the US Space Shuttles... if NASA is going to spend 5 years and 2 billion dollars working out the perfect exterior shape... why waste your own money trying to make it different?
Of course they didn't want their shuttle to be the same and it is actually rather different... think of the US space shuttle as an C-130 transport plane but because it is going on an enormously long trip it needs an enormous external fuel tank to carry all the fuel it needs, which makes it too heavy to move even at full engine power so two solid rocket boosters are needed to get it moving. The Buran is a glider that sits on top of a big powerful rocket called Energyia... you can actually replace the Buran with a fairing with a 120 ton object to launch directly into space if you want to, which makes it much more flexible and actually much cheaper...
