Thanks for your feedback. I added flash of light and snow on the mountain cap in entry #5 . I also try do combined the trees skyline in #6 , is it too busy for you? Let me know what you think. Thanks

Changing the slogan or colors wouldn't be a problem if you still not sure about it. You can ask me what kind of colors you would like to see. Thanks
