No worries. Please feel free to delete the ones that are not possible to go through, or add an appropriate difficulty.
On one of the changesets I did actually request a review. Thank you so much for reviewing this. It will help people like me have more fun the next time! 
I was there just now, over Easter, and it looks quite different than on aerial photos, that's for sure. :)
Also, you can cross check with BEV Inspire. Those photos are a bit different than Ortfoto.
But, since you know the area, please feel free to adjust as it is on the ground. Thanks again! I may get in touch with you when I'm back in the summer. ;)
