Maybe it works better in text-only.
I'm sure text can help in that you can get inner thoughts, or be able to suspend your disbelief because your imagination fills in the blanks. I think a visual format
can work, but I'd say that the CG models is probably working against you in that regard. Trying to show the gradual change means doing a lot of micro adjustments and almost remaking a whole model that might just be used for a few panels. So a lot of these CG comics tend to be "slow" but the jumps between steps in the feminization are usually pretty drastic.
Also, I think a major part of Sweet Change that makes it harder to buy that the MC still thinks they aren't being feminized is just how unclear it is what the level of conditioning (if any!) is happening. If the story supported it where we understood the MC's delusions, then I'd buy it a lot more.
Is it clear? The dialogue makes it seem like he's zoning out just because he's aroused.
As I mentioned, I hadn't really engaged in depth with Sweet Change as it's not a kind of WG content that I'm interested in. But there's a reoccuring type of interaction:
At least to me, there's this subtext of conditioning. I assumed there was some drugs helping, but maybe it's just a Pavlovian dog response? Sugar makes you feel good, so I'm associating sugar with feminization? I'll say, I do think the inner thoughts kind of let this down. I would have liked to see a lot more self-rationalization so that it feels more congruous rather than having a MC be weirdly subservient.
For example, I wish the build up into including heels into her wardrobe was better integrated. In a "unknowing feminization" story I'm writing, for instance, I have the "hypnotizer" seed in a few different aspects in preparation to make the wearing of heels a desire and something that the feminized target does to themselves.
1) Conditioning to change their outlook on female clothes. Change it so that the repulsion to wearing them isn't "I'm a man and I shouldn't wear women's clothes" to "I don't wear those types of clothes because it's something I've never done before and I'm scared of new tings".
2) Introduce insecurities about their height. Make it so that the feeling of being taller in heels helps tackle that insecurity (and thus associate it with a feeling of being empowered/sexy).
3) Condition curiosity via a role model. For a female dominant, it can be as simple as making a show of putting them on or off at the door. Make the feminized target long to try them.
Basically, show how our feminized target is gaslighting themselves into feminizing themselves.
