25 pages is not so bad.
My BSc(Agricultural Sc) thesis paper was 140 pages long and my MSc(BioE) thesis paper was 150+ pages long and all the research was conducted personally over the course of four years.
That should make you feel better about having to write a "short" paper, eh
At least my primary research was done working on ocean salmon farms in beautiful areas like Clayquot Sound (near Tofino) and at Broughton Island (outside Port McNeil).
