Will TESO artistic concept art for the never explored areas of TES influence the concept art and future developmentof TES games?

I hope not , not because I do not like but I think that TES developers shoudl be free to use their own imagination and inspiration freely without beeing chained by the overexpansion of the TESO universe.

No, single player games can have much better graphics and art style than MMOs.
I doubt it's going to have an effect anyway.

I voted no.

I do not mean about graphics but general aestethics ...

PersonallyI like the Hindu / Thai style for Khajiits and the Aztec one for Argonians , but will TES keep that orientation or make their own completely undependant?

Well they seem to change things around a bit each new TES game, I liked the Skyrim aesthetics, an improvement of that would be fine for me.

What architecture? half of the concept art in ESO is influenced by Skyrim and previous TES titles in the first place, and even then its still not as impressing. it all looks painfully average.
