Very interesting designs! I like #23 the font for Green Sp;rings is quite nice, could you make it a little thicker (but not as thick as #20 or #21). I also like the symbol a lot in the thumbnail, but it doesn't look quite right in the full size picture. I guess it looks a little grainy and hand-drawn. I am not sure how to explain it, but if you look at #20 for example, it looks "sharp" when in full size. Also, it would be nice to make the petals of that symbol different colors (colors should be not too bright though, more relaxing pastel-like colors). I look forward to seeing the revisions!
