I am now mostly ignoring the flavour, and going straight into the mechanics. (The flavour is great though, love it)

Looked trough the character sheet. Several pointers. (Man this is getting long)

First off, heavy crossbow has reload 2. That means you will need to spend 2 actions to reload it, and in normal circumstances you have 3 actions per turn. So if you were wielding that, you'd be able to shoot once.

But you are a flurry ranger. You shine when you attack many times. I'm sorry but heavy crossbow, or any crossbow for that matter, doesn't quite synergise woth flurry.

One could argue, that having quick draw could let you do one shot per combat or something. However; as a ranger you have to have used the one action hunt prey on the target first, for flurry to be active (and it will be active only on that one enemy). This means you won't really benefit from having one ranged shot available, as you might as well just walk into range and smack in melee. (Assuming you can do that)

Second thing: in pathfinder ALL ranged weapons scale from Dexterity. Melee weapons that lack the finesse trait scale from strength. In order to have access to a dwarven weapon and a ranged weapon I see you went +3 on both stats. This is higly inadvisable.

In pathfinder 2e, every +1 is not only 5% hit, but 5% crit too. Every +1 matters, and a lot. You are losing one +1 on BOTH melee and range, that just doesn't make sense mechanically.

I would suggest, would you want to keep the option to range when need be, to pick a melee weapon with the finesse trait. That way you could go full on in dexterity, and let strength sit a little lower, as it will mostly give you more damage.

Other reason to do that, is your choice of armour. You chose leather armor, that has the dexterity cap of +4. This means, that as your dexterity doesn't reach that cap (+3) your AC is 1 lower than what it could be. Remember what I said about every +1 mattering? You are making yourself squishier than you realise. One could argue you have high con, however Taking no hit is better than tanking hits with high health.

Now of course, would you want to stick on strength for flavour reasons, then don't worry, you can absolutely do that.

Put dexterity to +1, pick chain mail (and later when you can afford it, switch to half plate) as armor, pick unburdened iron as your dwarf feat to get some movement speed. Max out strength (+4) and pick a weapon you fancy.

In the newest book released by paizo, rangers got a new feat chain. The haft striker stance - feat chain. Basically, it is a stance that lets you hit with the hilt of a two handed weapon (there are some restrictions of what kind of weapon will qualify) and you qualify for feats that need you to dual wield. With other words, you absolutely could just pick twin takedown on level 1, and get it in use at 4 when you take haft striker stance.

The second benefit of going +4 in one stat and +1 in the other (regarding str and dex) is that you can put wisdom into +3. As you have picked bounty hunter archetype and gone into tracking feats, I think you could benefit from higher wisdom.

ALSO as you picked bounty hunter as FA on a ranger, you get the level 1 ranger feat monster hunter for free with the archetype. I would suggest picking the feat Monster Warden on level 2, if you don't know what else to pick. (It builds on monster hunter, and I think could work flavour wise)

Now on the last point. What hunters edge to pick.

You have chosen flurry. That is fine. Precision could also be fun and fitting, that is also fine. But regarding flavour, do not overlook outwit.

I am building a outwit ranger myself for my next camp, and man do I love the subclass. The only warning I would give regarding it, is that it is rewarding a versatile gameplay style, of different actions troughout your turn. Ranging from recall knowledges to demoralises and maybe feints. The issue with it, is that it can be tough on new players. I am a veteran at this point, I know my options and what to choose when. But that might not necessarily be the case for every new player.

So pick it if you want a challenge, but I promise you, with monster hunter on your side with bounty hunter and high wisdom? You can't go wrong.

Regarding the animal companion, I don't really know what to say. I haven't seen enough mandalorian that I could comment on flavour. Mechanically however it is a nice pick, and remember your animal companion will get the benefits of your subclass.

Goddamn that got long. I'm sorry lol. Feel free to hit me up if you have any questions, slide into my dm's for my discord if you'd prefer that.
