I am okay with Quartz as a luxury. One of the reasons I don't play with Even More Resources is that it adds too many Mine/Quarry Bonus Resources, so Mine/Quarry Pantheons become too strong too often. In the VP Mines are only used on Luxuries and Strategics, and Quarry is additionally used only on Stone Bonus Resource (which is already quite strong), so adding Bonus Mines/Quarries really hurts the balance. On top of that it adds 3 Mine/Quarry Luxury Resources, so the odds of you picking one those two strong Pantheons increase even more. I don't remember how many luxuries of each Improvement type there is, but I think there should be an equal amount of each so that the variety is at maximum. One Quarry luxury is not a big deal though.
The other thing to consider is that Quartz would be a land based +10%
Monopoly, which would be much harder to disrupt compared to Whales, which you can often pretty easily pillage with ships, without the need to wage a land war. I am not saying this is bad, in fact I think it could be an interesting new addition (especially for oceanless maps and pangeas), but this should be considered in terms of balance and snowballing effect. Additionally, Whales are very often assigned as either a "worldwide" Luxury, or as a City-State Luxury, making it very hard to achieve a Monopoly, unless you take Statecraft (enemies can still conquer CSs to deny such Monopoly), but with added Quartz you can now sometimes get +20%
in mid-late game (or even +40% if you go Imperialism).

Now, with Alpacas and Camels, I don't really get why they are Luxury Resources, and not Bonus. I think of Alpacas as Sheeps and Camels as Horses, but as local variants. Obviously, they are not the same, but they are at the same level of functionality in human societies. I could be wrong, but I don't think Alpacas or Camels were ever a luxury throughout human history for any nation. Why would anyone buy them for huge amounts of money?
I don't like the inconsistency introduced by adding two Pasture Luxuries. And, again, current Pantheons aren't balanced for Pasture Luxuries, getting 8 additional Pastures on top of usually abundant Sheeps and Cows can make an undeserved OP start. This is a reversed problem of Mine/Quarry Bonus Resources in EVM - there is just too many Pasture Bonus Resources to add Pasture Luxuries.
Additionally, some Civs have unique Camel units, which do not require Camels, which I always assumed meant there was just
so many camels around the places they live in, that there was no need to count. By introducing Camel resource as a Luxury, we will have a funny situation where a civ can build unlimited amounts of Camels without Camels, simultaneously trading "rare luxurious" Camels to other nations, or - even funnier - buying it. This is just too messy and inconsistent, they are either luxurious or abundant.

But I like Camels as a Bonus Resource found in deserts, this does not contradict their abundancy, buffs desert tiles, and gives more variety to every map, while Luxury Camels would sometimes simply replace your starting Luxuries, which I think already have enough variety.
I like Alpacas also as a Bonus Resource, as a variation of Sheeps, which can get boring with how abundunt they are (also kinda weak in mid-late game). I like the idea that there could be similar resources with slightly different yields and different order you get upgrades for them. Maybe even make them spawn as a "local" resource in some portion of the map (kinda like Camels are only found in deserts) or on a different continent, or even only on Hills surrounded by at least two Mountains. I don't know if I would like Alpacas everywhere, they are not as abundant as sheeps or goats worldwide (which nevertheless doesn't make them a luxury).
. But I see it works very well with you too. Surely quite a bit of talent too 
production with no real connection, in my opinion. Keeping this bonus for a land and sea luxury resource seems good to me. Maybe decrease it to 5%? And maybe differentiate the bonus buildings?
