I like your take on the icon at this point the best - so thank you for joining the contest... I'd like to see this icon a little more stylised and edgier. Im not sure about the tail??? Maybe the tail could form an 'under line'? just a suggestion :)
I would also like to see NEXA bold or light used as the primary typeface (for the do see go) in lowercase and/or upper case (one or the other).
I would like to see the grey substantially darker and more powerful perhaps as the background colour with the "do" and "go" in white and the "see" in that green (perhaps the green can also be pushed and experimented with also with some more yellow/mustard tones). I think the characters in do should touch and slightly join, the same with both see and go. With a very small space between each of the 3 words. isolating each word slightly. perhaps the two "ee" in see could be slightly tilted up wards? To emphasis this a little better.
I hope this helps with some proposed revisions. great work so far.
