I don’t have a lot of love for your army list to be honest. With only four deployments, an unprotected BSB (why does he have a shield??), and the Scarecrow Banner, I’m just not sure where your army list is going.
I would drop the two banners and proxy another blunderbus with those points. Also Im not a big fan of the hellbound rules maybe trade that in for a dawnstone for your bsb? Gives him a little more survivability.
i would split the blunder bussers into to separate units to protect the flanks

Split the blunderbusses and you lose their most potent special rules though. I don't have tamurkhan to hand so can't remember the exact prequisites but I'm sure you need more than 20 for the re roll to wound.
Notwithstanding the loss of the reroll to wound I am liking the idea of splitting the blunderbuss- doing this and dropping the full command gets me a 16 man and a 17 man unit to protect the flanks of the warriors and the magma cannon.
I’d deploy the blunderbusses 10X3 and the guard unit 7X3. Use the destroyer on the flanks. You don’t need hellbound on the cannon. I had an extra 20pts left so put the blood of hashut on your general. Can work well in some situations.
Also please note both characters now have a 2+ save followed by a 4+ ward save.
With Time of Madness’s list, you can ditch the Crown of Command for something else. But when you deploy, you’ll have to go at least eleven-wide to get twenty models shooting or you won’t get the full benefit.
