BNW cover is good as a whole idea, but Eddie is just a cloud - a really good one, created by the master Derek Riggs ! I always liked that cover !!!
DOD cover is not that bad, just all the things that surrounded Eddie are done in very low quality ! Eddie as the Grim Reaper is generally a good idea !
AMOLAD cover is a great one, but Eddie should be at the front ! the focus has to be on him, and the death soldiers and the tank has to be behind him ! great concept, at least.
TFF cover is 50/50, for me ! Not that great, but not bad. Again it has death soldiers and Eddie do not look like himself, but I think if the background was the cosmos , it would be so cool, or some spaceship !
TBOS cover is well done, but so simple ! Eddie is great (I preferred it in full stature), but that black background is kinda cool , but imagine if it was a pyramid with a jungle and Eddie - then it would be one of the best covers that Maiden has ! For the Book of Souls: Live Chapter I expected that kind of a cover, but they (I don't want to say again), went through the lazy way and released one of the tour posters for cover
Conclusion: some great ideas, but not that great works of art !
For me, Maiden album covers are specials, and for good sake, they have to bring Derek Riggs back or for the next album to bring Melvyn Grant , who created two very good looking covers: FOTD and VXI !!! My least favorite album cover is The X Factor ! all the 80's covers are amazing and NPFTD too !
