Hello Phillip!
Now that you started to buy ships, you will never be able to quit :-) Welcome Aboard!!!
Now, for real:
1 - Consider making it in sub assemblies (hull + deck) + (superstuctures) + (Air wing) and work them as "individuals", specially the air wing - I have seen excellent A/C models that are "ruined" because of a not so good airwing;
2 - Weathering: subtle enough to reveal some wear and details but should be invisible from, let's say 1,5 meter away! In 1/700 sometimes a little bit is already too much weathering - so use subtle tone changes and see pictures of the real subject and as you can see, it's there, but not that much

3 - Add ons, like PE sets make a dramatic improvement on these little beauties - so if you want to go that extra mile, buy some apropriate PE set and slowly work on it - remember that this will be very small and very very delicate parts! I can say that it is a time consuming task, but will look excellent
These are only some hints, if you need more help when you are working on it, please ask!
As Scott suggested, you could hold it until January 1st for the start of Garry Beebe's Flattops Campaign - you wouldn't be "alone"

Glad to see you around here, Phillip - I know that this Kuznetsov will turn out great!
Skipper
