Although including looks like a verb form, it's actually a preposition in your sentence. Here's how the Longman Dictionary of Contemporary English defines this particular preposition:
used to introduce something or someone that is part of a larger group or amount you have just mentioned [≠ excluding]:
- The price is £25.50, including postage and packing.
- You'll need a variety of skills, including leadership and negotiating.
We can tell it's a preposition and not a verb in this sentence because it doesn't predicate on anything. In other words, it has no subject. And that's okay—preposition phrases can function as adjuncts without predicating on anything, and that's exactly what's going on in your sentence.
So your sentence is fine.
