Why go for the more cell-shaded look? I remember playing Drunken Cowboy a long while ago and it using Celeste Star as the model in scenes. Was it changed so that you could add more images to the game when you couldn't find images that would fit the scenes with the model pictures like MDQP had issues occasionally?
Background was that I found Drunken Cowboy a number of years ago, and it was the first adult game that made me go wow. Take into account these games were totally free, the author got nothing for them, so the scene was full of small and abandoned games.
When I started CB:TEA the cell shading was a quick way to improve on 3Delight renders (using GIMP). As I've grown better with 3Delight, I'm now replacing them with better lit images. I actually tried making a free game with gifs and images, I picked a porn star with a lot of clips and started on a corruption game based in a hotel. It gets very tricky very soon with trying to find the right images, or making scenes around what you have. Then you have the issues of malware when you scour the internet for ripped gifs.
Dude I remember this game from ages ago, its still not finished, wow.
It is not good, but it all comes down to how much time is available to work on the game. I've got a full time + job and other commitments. Game has been going on for 3 years, which is way longer than I wanted. I know plenty of other games with similar development times, and fuck loads where the author has just walked away and abandoned it.
