You might want to be sure the top of the bottle she's in is tall enough that either one can't jump over it. Bettas are fantastic jumpers !
Looks good, though I used a hurricane lamp...what you've set up there looks just about as good.
Wait for the male to have a good size bubble nest and the female will show verticle stripes and take a head down position when the male comes near...you will also notice the ovipositor at her vent will be very obvious when she's ready to toss some eggs.
Keep an eye on them during the process and make sure there is something in the tank for the female to hide if she needs to.
All the best in your efforts Fishinme ! Do think about what you will be putting any fry in that you get. You will most likely not have to seperate them before 3 months though, just be sure to have something setup and ready for when you do !
