Like the idea of a pictorial or abstract mark, similar to what you show in Entries #21 and #22. Some comments:
1. Would it be possible to make the 2 smaller and more of a subscript? 2. Trying to determine if the abstract images in these logos depict the benefit of our equipment and service, which is to increase oxygen levels in the soil.
Would like to see #18/19 design with these changes: 1. make the 2 subscript like you did in #26 & #27 2. change the graphic from raindrop shape to circular with blue on the bottom half and green on the top half
