First grid, any feedback is much appreciated!

Thanks TJB. Difficult to give feedback on the grid because I didn’t have a clue with two of the groups, so no idea if there are any red herrings in there. There is a spelling mistake which took me off track for a bit. Anyway, I got 2 groups with the links for each one. To get the others would have needed me to hit a 6-1 shot because I was down to pure luck with the 3 attempts at the end. Thank you :)

Good stuff. 10/10 in 1:30 for me. I'm currently reading a book which coincides nicely with this grid, so that helped. Only one red herring that I spotted, and I found the Nestor group with some reasonable guesses at the 2 tiles I wasn't sure of. Only got the Stall link after the wall resolved. Not super-hard, but a nice work-out.

Apart from sp of cannon a good grid. Stall group was fun. Try more crossovers that throw people off. Thanks

Thanks for the feedback - clear and constructive! Today I learned - the Japanese photography company Canon does not spell cannon correctly. Duly noted!
