Please keep working on the text used in #5. I prefer this text to all the other designs. Just need some different symbols. Also try the symbol sitting above the text. Definitely stick to one colour on black or grey.
Could be nice if the symbol hints at the illusion of a 3D space being created. A lot of what I do is based on creating internal spaces like exhibition stands for shows and fairs. One thing that slightly sets FlowCreation aside from other companies is the artistic and creative thought behind the designs.
