Hi
That's certainly looking a stronger position. I'd still argue with your city placement, of course, and some of your city improvements look suspect to me.
For example, you have Sun Tzu and you are building Leonardo's, but you say you are a builder. These are military wonders.
You have three cities at distance 4.5 from Salamanca. These are at corruption rank 1, so they'll never need courthouses. Using RCP you needed to build more cities at 4.0 or 4.5, as every other city is now at corruption rank 4 or more, having 4 cities closer to the palace.
You have a single galley, and it's asleep, yet there are two civs ou there that you haven't met yet. They represent trading opportunities. You should be sending out suicide galleys to reach those civs.
I never, ever build defenders. Defence is best achieved using attacking units, as they are far more flexible. A pike has an attack strength of 1 - no better than a warrior. All he can do is stand there and hope. If the AI gets to attack your cities you have already failed.
Cathedrals are only of value if you are planning a cultural victory, or when you have cities above pop 12, much later in the game. Meanwhile they are costing you 2gpt that could be spent elsewhere. Even temples are of questionable value unless you have severe happiness issues. Speaking of which, you need more luxuries to make your markets work. Since there appear to be none for sale, you need to get out there and acquire them by force. Salamanca is your unhappy city, requiring yuo to set your lux slider to 10%. You need more happy pills in Salamanca to allow it to grow.
You also have several non-productive citizens - entertainers do nothing for you unless your cities are rioting. Either put them to work to grow the city and/or to create wealth and shields, or in a corrupt city that can't grow any more, make them into taxmen to boost your revenues.
I guess the main question I have is what victory target do you have? If military then you don't need all those temples and pikes. You need knights. If cultural then you have already missed the boat, as the AI has all the major cultural wonders. Diplo or space are the other options. I have little experience of these, so I'll leave others to comment, but fast victories in either case rely on fast research. If this is where you are going you should be researching at maximum speed.
Hope these pointers are helpful ... you did ask !
