I am very frugal, so I don't want to pay more money, but I don't think you will make enough money if the top tier is $7. I am not an expert, but looking at other Patreons, it seems that a small number of people at the higher tiers bring in most of the money. You still make some good money at the lower tiers, but most of the money is made at the higher tiers.

I have already paid for the VWD program, so I don't want to pay a lot of money for updates, so $3 for that is reasonable. But if you're making clothing, then that can be $5 to $20 depending on the quality. Video tutorial can also be $5 to $20 depending on quality.

Also, can you actually produce all these things each month? If people pay monthly, then they expect new things each month. Very few DAZ artists are fast enough to produce a new piece of clothing each month (though you don't need to produce such high quality clothing maybe). Otherwise, it might be better to do things per release. Or throw in some textures instead of new clothing or something like that.
