Aquasea Business Logo - Environmental/ Water Quality Projects

This is what Aquasea Enterprises / or just 'Aquasea' was looking for in their logo design

Aquasea Enterprises is a small niche environmental consultancy that specialises in sustainable land/ water projects in Australia - adjacent to and within the Great Barrier Reef Region. More info attached.
My original idea was to utilise a Yin-yang inspired symbol to represent 'balance' and have one half of the logo represent the 'terrestrial' (land) component and the other half as 'water' (ocean/reef) , both connected and interdependent for sustainable development/ communities.
Attached is something I generated with AI, but could not get the refinement in the logo elements that i was looking for.
I have also added a sketch with some ideas, but as you can see... I'm no graphic designer!
I would consider 'other ideas' that anyone has that may better reflect my business image or philosophy. (Capability statement for my business also attached for additional insights)
Thank you. Read more
