#38 has the elements inside the shape of a play button, indicating while parts working together to create ability to move forward
36 has sort of a cascading element effect almost like a wave, which again has one thing leading to another to create forward motion
If you ever see any of my entries you would like to see variations on (colors, fonts, additions, subtractions, adjustments to form or just suggestions), please let me know. Happy to do. Thanks C
#35/#36 is a little too abstract or flowery or peacock-like...
#34/#45 the star is too crazy and colors of #34 might be suitable for a romantic beach-bar at sunset... :-)
#31/#48 play-button is nice idea, but if at all I'd chose FF-button (double the play-button), which would make the other elements hard to position. In #41 the black elements suddenly became footsteps in my eyes :-o
I like the flat PCS-font... looks suitable for the lower space beneath a car's door.
#46 is nice and straight... though or maybe because it's almost what we have already :-)
