Logancure, Tixnen, Nyx, Cloud D, Cutepet, Krysdecker, Demonlorddante and YAM_Spectrum all come to mind, though I have no idea who, if any of them, take requests. Not many artists do from my understanding, preferring to just poll their subscribers.
Personally, while I'm not a fan of hetero/preggo content, I do agree the '19 Mai set was lacking (which is part of why I think she's earned another place in dandon's gallery). The pose was great, IMO, something about doggy-style boobs hanging down just gets me going, but the absence of variety in the content was disappointing (not even an alt-outfit, and there wasn't anything really preventing tentacle variants as well). For me, fingers crossed she wins (likely, but you never know) and looking forward to what dandon cooks up.
Sorry, anybody knows where to find cloud d stuff.
I'm preferring Fubuki, but Commander White would be a nice surprise (unlikely as it is).
I used to know, but the good stuff is all gone now. All I can do is go to Pixiv and Artstation...
All clues point to him quitting or at least focusing on him being a full time painter. His Artstation page hasn't seen any love for a few years.
Depends how 'similar' you want them to be, as dandon's still pretty distinctive in style (unlike, say, Sakimichan, whose style, though once more or less unique to her, is pretty heavily cribbed these days). Other artists not suggested you might like are dantewontdie (think he's no longer active now, though), lera pi, goatwillow, limgae, queasys, and xxoom. Don't think they take requests except as community polls, you can always ask if they accept commissions, though.
I personally loved arion69's art works and suddenly he's gone kinda south.
Probably not the best person to help 'cos I'm not much of fan of that 'true-to-life' 3D style (a little too uncanny valley for my tastes, while a lot of it has now been co-opted by AI art generators, which is a pity). Maybe ninjartist and demonlorddante as they do something along those lines.
