Also to offer something specific to the question you posed, you aren't really locked into a quality level yet. If things are "hyper"detailed for the hot springs scene or just this first arc, the art can easily settle into a more stable "rougher" format from now on if you want. Think of the intro as really getting players set and into the characters and the scene. The same way that dojinshi usually release the first couple pages in full color and then just, continue on with the plot in black and white. It's totally whatever works for the project and wouldn't ruin anything whatever you chose moving forward. People are obviously eager to see what comes next though lol.
I'm debating whether I should tone down the detail and polish to speed up development for future updates, or stick with the standard I've set until we can afford to bring on another artist to help with it or do backgrounds.
