The second one. The 3rd head of the first version seems to me having a little weird angle.
BTW, I didn't find the time yet to say to you that you're really doing a good job
If you are going to put them in a mod, I think they would fit perfectly as late-game unique summons - some kind of elemental royalty of the natural disasters ^_^ but requiring different paths from one to another... just my thought of course
Good job again.
Peace
