I think your inclination toward rustic and distressed pieces is the right way to go. Consider a movable coffee table - I see 2 recliners that may necessitate some table shifting?- an area rug large enough to incorporate all the seating, rather than just a hearth rug, and enclosed storage for your electronics. If you can post shots of the room, other Houzers may have some more ideas.

The welcoming bronze Idol with flower garland in the hands is a cute idea. And the walkway to reach Radha Krishna in the Brindhavan wading through a stream of water & pebbles is a uniquely brilliant idea which simply stands apart from the herd thinking. The designer has actually mimicked a mini version of Brindavanam. And a center hanging bell is awesome. Hats off to his creative thinking.

One of my clients had no designated space for puja in their home, and they would have had to squeeze it into a passage somewhere. So when they came to me for ideas, I noticed in the floor plan that they had a beautiful covered verandah overlooking a private garden. The wall of that verandah was towards the east side of the garden. So I thought- why not carve out a rustic simple puja space here? Outdoors? The client was game. And this was the result- a 2'-0" x 2'-6" wood panelled niche in the wall, with a simple clay Krishna placed on a wooden bracket with a delicate hanging brass lamp

Its just really messy right now. Too many colours and clashing prints. Is that Puja unit lime green? Or does it just appear that way because of lighting? Either way, it stands out like one more distraction. Pick one base colour add and add prints that go with that base. That TV unit HAS to go. So do that black metal coffee table and the carpet. I would suggest you go with a simple geometric print in the carpet. But apart from these obvious design gaffes, the structure has distinct possibilities, if you do a classic English style. The railing above adds some interest
