#42 - Please make some experiments with the sphere from the first samples. Like the 'wavy' or 'windy' particles comes to form a sphere, kind of a snapshot in action:)
#67 - Good idea with the particles. Please use more bold (or different) font. Also please make some experiments with the particles too. Good idea for start.
#51, #56, #57, #61, #62, #64, #66, #68 - They are OK, but not so fancy:) As others please keep trying the experiments with the shape (and font).
#52, #53 - Interesting, but colors (especially green) is not quite good. Also you could use another (more sharp) font, and make the shape more fancy (some effects etc).
#83 and others with the cyber-leaf - maybe it is an idea, but not like this.
#21, #22 - Quite good idea with the shape, but use the warmer green and we expect the shape more fancy:)
