Hey there!
So, for patreon, is all based on the perks but, you always get the patreon packs if you contribute with more than U$ 20
In the end, each pack has a number of drawings depending on the current commissions and prizes, but, the packs are cummulative so, entering now, for example, you will receive links for all the past packs just as well (and that´s a LOT of drawings, that I assure you! XD)
