Thanks all for your kind comments and thanks steadyhands for the NDGrad info. Will try to improve on the slanted horizon thing.
I used a gitzo 1220 with manfrotto ballhead( I'm not sure, just borrowed my buddy's tripod) with Nikon FM2 and Sigma EX 20/1.8. Used Fuji superia 100( Wish i had used slides :cry: ) Exposures were all done using bulb setting at f22. I think approx 15-30s( by my estimation of 1000,2000... )
except for #4 which was 1/125/f16
