@demon767 I'm not sure whether you mean 'image size', 'image dimension', or 'number of variations' by 'smaller art'
From what i know, it seems the artist encountered some health/mental issues back in 2021 and it dragged on to 2022. It noticeably delayed his patreon rewards (he is SIX MONTHS behind schedule). He also stops awarding new 'exclusive sets' to patreon subscribers (used to be the 04, 08, 12, 16, etc. set number). That might also explain the 'smaller art', to reduce his workload?
Though, this gallery is way back in 2020, so if you base your question on that, my answer is completely off the mark lol.
@xD1993 Thank you very much. I didn't know that. Hope the artist can recover soon and the best for him. He is THE BEST hentai artist a have ever known. Thank you so much for the information and have a good day. Peace.
