It's technically and superficially breathtaking, but on closer inspection, it's a mishmash of styles across like 500 years.

- gold everywhere is excessive - more Rococo (1730s-1760s) than Renaissance (1300-1600 roughly), which was a lot more restrained

- mirror way too big and clear. Renaissance mirrors were small polished metal or darker imperfect glass

- candelabras too ornate and numerous for Renaissance. Multi tier candleholders are more Baroque (1600-1750), and candles look suspiciously perfect, as opposed to period-appropriate uneven tallow or beeswax

- white paper too pristine (parchment or vellum would be expected), pen holders hilariously modern, gold-plated(??) desk surface is absurd

- woman's clothing looks too recent (Victorian?); sleeves and hair are theatrical

- hard to tell, but background dudes are lurking in what look like theatrical costumes rather than anything historically accurate
