Cape Cod 3D Beam Rendering

I need a 3D rendering for a large renovation project. We're vaulting the ceiling in an old Cape Cod house and adding 6 exposed structural wood beams (see floor plan w/ beams and frame plan), but I'm unsure if the beams will be fully 'floating' or partially exposed through drywall, based on where they will be located and if we take the walls for the closet next to the fireplace up to the ceiling or not. Fireplace will go all the way to the top of the vaulted ceiling - but there will be a flat seam at the crest of the vaulted ceiling (which is defined by the concrete collar atop the fireplace in the attic - see attic photo), which will go perpendicular to the beams (but well above them), so the vaulting doesn't go to a pointed intersection. Beams will start about a 1/3 of the way up the vaulted ceiling from the top of the walls, which are 7' high. Ideally, 4 beams will be in the living room, starting with 2 on center from the fireplace, as close as possible to each edge of the 6' wide fireplace. Additionally, in the adjoining bedroom/bath, the beams will continue but with only 2 beams in that room, it might look strange b/c one will be in the center of the room and the other will be against the far wall. The ceiling in these rooms will come down to the top of the beams, rather than let them float, and the wall b/w the bedroom and bathroom will go all the way to the ceiling. I'm looking for rendering of all these areas to know how best to proceed.

Key Requirements:
- 3D rendering of vaulted ceiling with wood beams in living room/kitchen and bedroom/bathroom
- Suggestions for beam exposure (floating vs. drywall) - need symmetry in each room, doesn't make sense for room w/ 4 beams to have just one going thru drywall
- Cape Cod design style adherence

Ideal Skills:
- Expertise in 3D rendering
- Experience with architectural design, especially in Cape Cod style
- Knowledge of beam design and vaulted ceilings
