Thank you very much for your good wishes.

I think it is quite natural for Russians to greet people by referring to their настроение.  However, in English, it is not usual to greet people by wishing them a good mood, or by asking them about their mood -- especially when that's all you are going to say.  It is more typical to say something like, "I hope you're all doing well", or "I hope you're all in a high spirits", or "I hope you're all feeling fine".   If you want to "wish" something, you could say, "Have a nice day!  I wish you all the best."
