That's a tough one; ideally you want a wide angle, but depending on the details of statues or paintings, you may want a zoom. I shoot some Christmas pics for my church's high mass and ended up using my 24-70 with a 1600-2200 ISO on a D750. You may also want to look for a local church or cathedral near you for practice and offer them some free pics. Enjoy your trip!
Yongnuo makes good products at a reasonable price, but it's also worth looking on craigslist for a used Nikon SB 700.
It may be worth listing them on Craigslist.
I would love to see them....great shots.
Great color, in the third one, it looks like the rock is floating above the water.
Those are some great pics!
Great set! Thanks for sharing.
Regardless of what colors look like to you, a good picture has good composition and you can see composition.
Stick with what you enjoy!
