riceral, that recipe looks pretty good. Here's the tweaks I would suggest:
Mash hot and fast, about 153 F for just 30 minutes, to ensure a higher final gravity. Otherwise it's going down to about 1.020, which is okay but perhaps not in line with your goal of 1.025.
Maybe try a different yeast such as Wyeast 2206 or 2308, or the dry W-34/70, rather than S-23 that would make it more fruity.
Consider trading some of your chocolate malt for black patent for even more complexity.
Also consider that your efficiency might suck with a big beer like this. If you normally get 75% efficiency with 1.060 beers, keep in mind that your efficiency might drop to as low as 50% for a monster like this. If you set up your brewing software like this, you are more likely to achieve your OG goal of 1.085. Otherwise you might only hit 1.060s or 70s.
The above tweaks are all optional. Recipe looks pretty tasty as it is! Enjoy.
