#5 is the best entries of wep. What I don't feel as 'mine logo' is the image...I cannot see the immediate linking with digital...maybe in this case you have to think about something different from the on/off button stylized...
#5 is your best logo I think we can start from #5 but we have to change the character. What do you think about using something similar to 'Star Trek' / digital character? I see few characters nice in the contest... You can replace the light blue with silver in the image (like #4 but silver has to be a little bit more dark). Then you can use silver for NEW and blue for START UP. Please add also the pay off under NEW START UP brand name Tks!
