It´s great to be working with you in this finalist phase. We really like your concept in #53. Can you make it larger, as in #39 but keep the yellow. Also, the yellow is still too light - it's hard to see against a white backdrop. Can you try a darker shade? Also, it would be interesting to see this logo with some 3D elements added to it.
For whichever logo we choose, we will want to see three versions - 1) a social media button that will work for our FB, Instagram and Twitter accounts. 2) A version that only has the graphic and Rads On A Plane and 3) A version that has both Rads On a Plane and the tagline incorporated.
It's going to be a hard choice. We feel very fortunate to have received such wonderful designs. Thank you for your very creative submissions.
