Agree with most here. It’s not the concepts that needs sprucing up, but the presentation and final last 10% of details that you need to focus on to really make sing.
Example the connection between the screen and leather worries me. The edge treatment of the strap, the ease of use of that buckle design. The colorways/material choices and how they speak top different consumers. even down to the choice of watch its paired with.
Dialing these details in will take it from cool idea, to wow I need that right now.
What employers want to see is not only that you can come up with cool concepts, but that you can come up with cool, executable concepts.
