I think I like 40 better than #43... I like the text layout better, and if the tagline were shorted to "Transition it Yourself", it would fit better and be more crisp
I like the font of # 37, upper, lower better than all caps... hopefully you will see these comments tomorrow... I just looked and saw that you are based in Europe, and it is the middle of the night for you.
#47: this is looking really cool. a couple comments: the lower sign (with the tagline) does not seem to have the same perspective angle that the top sign has. Also, I would like to see the top sign with rounded edges, like #41.
I would also like to see what it looks like with the tagline below the blue swoosh on the top sign... and removing the bottom sign.
#54: This is getting very close. The gray gradient text does not stand out enough. Maybe having a thin black outline around the text would solve that. I think I would like the tagline in the sign, below the blue swoosh... as part of the large sign, not a separate little sign.
