I think I'm erring on the side of less is more. I was playing with some reflections and shadows, but not sure I want that in the design as it doesn't tend to translate well to print (especially fabric). Here's more along the lines of the monochromatic look and color I was going for:
Do that with #4 and I'll like it. Designs are pretty, but you need to make the name stand out. You can't do a search on a design. And the design in #4 looks active, like it's taking off. The others just look flat.
Of the originals 4 jumps out to me. Seems to be the best balanced to me. I'd like 1 & 2 better possibly with a touch more space between the graphic and txt. The bottom design on your second posting is good. How does it look dark on light? The top logo might work, but I want to see a more circular version of the sun element. I don't like it as an oval. #6 might be stellar if you could work on a more minimalist/abstract "41".
