Hello nice work ! . This is what I think ; photograph number 2 is similar to 1, so I will remove it from the serie , the same goes for picture number 5 which is similar to 7. And the last one should be better in color becasue as you know B & W add dramatism , the guy is smiling. If you have a picture where the pilots are preparing befor the race or a shot when the race is about to start in the goal line, should round this work.
