Agree 3rd one, though if you could somehow add something about the 1st one (controlling the environment) might look neat.
Idk about the symbol last i read they said it has to be seen and kept as noticeable and original to its shape as possible. Idk if we are allowed to change it any i tried and was told it was not what they were looking for. So i just slapped it on my characters foot, like a nike sign.
I had an idea i wanted to share and idk if you could do it (or allowed) but that 3rd img the 1 growth design make it the symbol they want, would look pretty neat i think. We will see check the brief some people been asking the same thing.
Checked this is what i was told:
That's a different logo so it wouldn't work. Think of it as a
company/brand logo, the outline/silhouette should be 99% the same (think
of the Nike logo, McDonalds, etc).
So there you go.
