Calm and sleepy, I like it :)
The instruments you used were really magical and helped create a peaceful and happy mood. The pads also sound sleepy, as if they are about to carry me away back to bed haha. The bass was a very nice addition, but wasn't harsh enough to throw off the atmosphere of the song. The progression was also familiar and slow, to help introduce a feeling of familiarity and further tranquility. Great stuff, keep it up!
