I'd be happy to work with you in the future on one of those country maps! But yes, I find people think my style is usually too 'perspective warped cartooning' for someone who wants a strict isometric... not that I don't have the rulers for it... have you considered going to SkinnerGames who made the last map you posted? Hmm, maybe you could also call on Lunatic Games on the forum, he mostly does top down battlemaps but they're pretty nice inked work. Kier on the forum does stunning battlemaps but more the 'rendered' look, still possibly a contender if inked lineart isn't a key component. And if you really can't find someone there's always Dungeon Scrawl which does generate an isometric layout! (it's a free tool)
