Looks good! Good to see Brockley Footpath on there.
Harefield Mews between Cranford/Harefield roads by Brockley station has some mean cobbles. Brockley deli there for a bit of fuel.
Also, by Hilly Fields, there is an alley from Overcliff Rd to hilly fields - Whitepost Lane I think. Starts with a 15 metre steep cobbled section at the Overcliff road end.
Disgracefully I've realised I've steered you slightly wrong - the tiny cobbled climb at the end of Whitepost Lane is the bit between Sandrock and Overcliff Road, as circled in the screenshot below.
