Congratulations on being the only designer to pick up on our idea of the i giving up it's dot to serve as the period. We like the direction of your design very much. We wanted to keep this idea subtle in our logo, and the arrow may be too direct. But we really like the idea of using graphics to hint at this transfer.
8 is the best of your submissions. The extra arc in blue distracts from the arrow, which is actually a good thing. More variations of this theme would be interesting.
Also like the "tightness" of your logo. Keeps everything centered around the word give, which is what we are aiming for.
