Some pics of the ballast after an overnight dry. Looking good (better in real life than in the pics, I think the granular quality of the ballast confuses my phone camera, and it doesn't know what to focus on?)
However, I am genuinely really pleased with the results - I still have little gaps to fill and the odd bump to flatten, but for my first outing it's not looking too shabby! Cleaned a small section of the rail tops as well (Sidings) and that always improves things I think.
