Artur, thank-you for your submission. I think your combination of the sun and wind is clever. I do not pick up much of an objibwa feel from it. This aspect is important because the founders of the organization are Ojibwa natives and they would like the logo to convey this, even subtly.
Some examples:

There is a softness to their art that conveys flow and connectedness of all things. It isn't perfectly symmetrical.
I hope my feedback is helpful.
