Looking at your model (!!) I'd strongly suggest making a choice now (0.1) about which direction you're going to go with your futa angle: either is fine, but you'll want to cater to either/or here.
Titles such as:
https://f95zone.to/threads/dungeon-slaves-v0-63-adn700.50888/ embrace the OTT physics-destroying (and anal gaping) routes. It appeals to a fairly small niche, but a strong one (check his Patreon out - 5.000++EU a month for that title alone, with 600+ Patreons so not an unlucrative one).
If you want your futa content (especially, dear god, your cat-futa has balls the size of a bulls') to be more vanilla / liked, I'd strongly suggest turning the slider down by a good 60%. Oh, and get the proportions correct: an aesthetic penis is slightly larger at the end, not the middle, it looks like abuse of pumps rather than a pleasing form*. There's a good example with a Demon/Angel pure female / futa cast that you can find on the forums here that really nails the correct proportions / aesthetics (I forget the name).
However: no real monsters, so good luck but not really my thing - and make that choice fast, it'll save you a lot of hassle / allow you to focus your design brief and target audience a lot quicker / more $$$. As a
general guideline those looking for cat-boy / fem-boi aesthetics don't like massive testicles / bulging in the middle penises - their tastes are a little less... Japanese, let us say. Load up "Harem Hotel" and start loving modelling willies is my advice if you're going for that market.

But anyhow, good luck.
TL;DR
Rhino sized dicks don't attract those looking for femboi stuff unless you go all in on the bit; given the amount of care you gave those eyes, probably not where you're going, so decrease the size by 60% or so (and especially the testicles,
NO-ONE WHO IS NOT HOMOSEXUAL HAS A TESTICLE FETISH and even then, it's rare as hell).

I'll def be keeping an eye on this for future updates.
