To me, the size isn't really an issue, that's fine, what does get to me a bit is the images (both CG and many of the character "sprites") look like they were scaled down from a larger resolution image, resulting in a lot of the non-aliased lines on the images missing pixels because the new image sizes do not have enough pixels to display the line(s) fully, especially noticeable on diagonal lines/details.
Something that is a common issue when you work in image editing software like Photoshop and scale down images without anti-aliasing on or not drawing the images originally at the needed resolution, even though this happens with anti-aliasing on too, it just generally takes a little more before it becomes noticeable.
I recently noticed this especially, since I've made a personal mod of Phoenix that edits her pants. Ever since I've seen it, I can't unsee it now. Lol. Here is an image of what I mean. (Not hating the developer, I do apologize if it comes across as that)
Left is the original image, right is the redrawn image (I just redrew it in black instead of a slightly lighter color), notice the look of the outlines in the original image.
Larger size (for ease of viewing)
While this would be a nice to have. I would personally like to see Kal focus on new content and fixing ongoing issues like the second picture instantly vanishing in the kitchen etc. Maybe this is something he can put effort into on image redo's, but again sounds like a massive time sink to refactor every single CG
