This is a rough mockup I came up with in around half-an-hour.
Your post falls to a few things that a lot of people seem to go for when they first start laying out pdfs and such in the rpg community. Namely a lot of textures, white-with-black outline, odd colour choices (inc. too much light-grey) as well as a lot of blue-rimmed boxes. It helps to only go two tones with an additional accent only if the colours acutally match. White and black are good opposites, as are black and white. Red goes well with both, as does reddish-oranges, darker blues and greens. Sky blue, white and stone grey isn't a very pleasant colour scheme to look at.
>Cornathian Navy Savage Class Breaching Shuttle + following text.
Minor nitpicks. Black doesn't look good on grey, especially if it's a textured background with a lot of black lining. Along with your body text (which I assume is a placeholder), I feel as if you are ESL, possibly German judging by the use of Kraft. It might be a good idea to ask someone you know who is a natural english speaker to go over your paragraphs as I noticed a lot of odd sentences. A better title to use would be [
Name of shipyard] (e.g. FT Rockworks) [
Class Name] (Viper-class, make sure to add a dash in the class name) [
Ship Role] (Raiding vessel). You can then determine what the main buyer or user is in any descriptive text. "The Felthan Transcendency utilises the Viper class as ad-hoc privateers who gain income through the capture and repurposing of pirate ships in the Felthan subsector."
The slightly translucent white background over texture background is not unreadable, but nor is it attractive to the eye. The blue outline is arbitrary and looks very out of place and shabby. Its better for body text to not have much colour variation except to point out text (E.g. "No
Denaar, please don't
Drive us off the cliff. No!"). A simple dark-grey/black and white, or white on black is the best option in almost every case. Fantasy RPG's can sometimes get away with very light sand/tan towns with black text.
>The Art
The art is fine, but it should be made into a PNG with a slight white glow effect around the rims if its on a black background or with no glow on a white background. As for the deckplan, try to use White-with-black-outline text sparingly. It is readable in most instances, but grey-with-black-grid actually counteracts this effect. In general white-with-black-outline is not an attractive title use. It is better to have a black background with bold white text or vice versa for maximum readability.
>Ship stats
Same issue as the body text and such, too many arbitrary design decisions. Simple is better for the most part. Nothing here is unreadable however.
