As an editor for the Little White Butterflies scanlation group, it's painfully obvious to me that your scans aren't leveled and that they're bloated in filesize, because you saved them as RGB color instead of greyscale. I know your files are bloated because the RAW is only 16.15 MB, while your project is 59.38 MB. I can tell your scans aren't leveled because the speech bubbles are all shades of beige and grey instead of pure white, in addition to areas that are supposed to be pure black looking grey.
This will teach you how to level your scans, even if you don't use Photoshop: http://www.ruinevil.com/rawr/editguide/1.html#3
Assuming you use Photoshop, to change your file type to greyscale, at the top menu: go to "Image", then "Mode", and finally "Greyscale". From there, save your files as 32-color (or 64-color) B/W PNG files to reduce bloat. A general rule of thumb is that your project's filesize shouldn't be significantly larger than the RAW files.
And as an added bonus, I took page 3, applied both of the above principles I mentioned (in addition to cleaning the gutter shadow on the left hand side), and turned a 4.12 MB mess into a better looking, 938 KB file. Here's a glimpse of a properly leveled and cleaned page 3 (the top part, anyway), which is what all your pages should look like: https://puu.sh/FXGkj/791e975d69.png
Best part is, it doesn't take too long. This took me about a few minutes, tops, but it makes the project look a million times better. If you want to make your works stand out, you have to step your game up. Properly leveling and converting scans to greyscale is a good way to begin to improve your scanlations.
