I think the thing that makes the road markings by the dodgems seem a bit odd to me is the fact that they don't fully extend the width of the path, just seems slightly off in my opinnion.
Regarding the whole sparkle project, I think that Thorpe's intention is with it is great, I love that they are investing into the maintaince of the park. However, it just seems that the execution isn't quite there; the new additions just seem a bit cheap/tacky in some places. I'm still waiting to see these in person so I can't make a full judgement yet, but for me it just doesn't quite seem it.
