You did try something! Fantastic progress. We really like how #44 looks when compared to #14. It's a very good improvement. #44 looks simple and clear to the work that we are doing. We also like how the colors are vibrant.
You are right, #46 looks very clean and professional and more stable than #42. However, #42 has its own uniqueness because it looks 3D and different from the rest. Nevertheless, #46 is what we like better. We like #45, but #46 is just a better version.
Can you try something different with the wind on #46? The wind can make it look a little more complex than we want it to. For example, we like the simplicity and boldness of #44 and 3D quality of #46.
We like how #43 looks, however the symbol looks a little detached and not very cohesive.
So, for now, we like #44, 46 and 14.
