Is Elbaf based of Norse Mythology..?

This is the picture of Yggdrasil..
It based on Norse Mythology..
What catch my eyes are the mounts at the middle..
Is this resemble this panel from One Piece..?

Look at both picture..
Is it look like the same to each other..
Could it be that Elbaf is based on Norse Mythology..
I think it is YES for me..

But..
Is that all reference that Oda saved in his sleeve..?
What about the nine worlds..?
Yeah..
Midgard is based on the human world..
There are giant world too in Norse Mythology..
Look clearly in the picture below..

There are FOUR Islands beside Midgard..
Muspelheim : the land of fire
Jotunheim : the land of giants
Svartalvheim : the land of dwarves and black elves
Nivlheim : the land of Ice and mist
I think the concept of summer, spring, autumn and winter islands in One Piece maybe based on this..

What do you think of Jotunheim..
Could Saul the giant that help Robin at Ohara comes from there..?
Are Elbaf is based on Asgard..?
- This is because Loki was from Asgard.. Right?
Or Elbaf are based on Jotunheim..?

Plus there is huge tree as the main link to Midgard and Vigrid..
Before reach Asgard.. There are two more islands which are:
Vanaheim : the land of the vanir
Alvheim : the land of elves

What comes to my mind right now is Vanaheim..
The land that got windmill..
Could it link to Nami..?
Because she makes tattoo of windmill..

I think that Oda used Norse Mythology from the start..
He planned to make use of information from Norse Mythology to create the seasons islands then create one more island which is sky island..

One more thing to consider..
Look at this picture of nine worlds in Norse Mythology..

This picture makes me think of the globe in Ohara..
The one that tell us about One Piece Worlds..

As Earth is in the middle..
It look like Midgard that are in the middle..

What do you guys think of this..?
