I think it is visually appealing and easy to read. I am not sure if you had a particular reason to choose those colors (maybe your favorites?). But with the name Sky High, is seems like blue and white would be relevant colors. Maybe a puffy white cloud passing behind the sky blue letters? Maybe even a light blue background overall, with the somewhat darker blue letters highlighted by a puffy, white cloud? Or something similar?
It is true that you don't want to get TOO detailed in a logo, so I don't know if you could make this work without getting too fussy. But it COULD be cute to have the words framed on either side by a couple of very tall stalks of corn, reaching up to the sky ("corn is as high as an elephant's eye", lol!). They would probably be too small to have scale patterns of corns and ball pythons, kind of like in my avatar. But maybe they could have suggestions of semi abstract snakes coming out of the tassels - or something? I am not an artist, but maybe you could play around with images and see if you can figure something that would click.
Just some ideas - don't know if they would work.
