Logo Design Brief
Finalize the logo design from the attached concept. We are an independent manufacturers rep firm in the security and audio visual markets. The name 4th tide is a nod to Industry 4.0 (IIoT, 4th industrial revolution, digital transformation). Overall the logo is 4th tide, but hidden in that is a "4.0" Currently the logo has the bottom of the 4 representing the t in tide. The dot of the i also represents the dot in 4.0 and there is a wave that rolls back to represent the 0. I would also like a tag line of "Transforming Representation" included. Colors need to be ocean themed and the logo will be used for marketing materials such as shirts, pens, etc... so must be professional quality while remaining simple enough to be functional. Make adjustments as you see fit for the best look such as changing the fonts, rolling the wave over more or using a different wave design all together. If you prefer, you can start from scratch using the attached logo only as a guide.

I have reviewed with my team and we would like to see some more options before making our decision.
