The line widths of the gate and the typography are the same, yet the weight of the lines in the structure surrounding the gate are lighter. I’d be inclined to make the line weights the same or experiment around with those weights a little more. They just don’t seem to complement each other.
The small breaks or gaps between the lines are uncomfortably small and are on the verge of disappearing. I’d either make those gaps larger or remove them altogether.
Architectural themes in logos typically mimic the actual architecture associated with what the logo represents. I don’t know what gate city is, but is it a city? Does it have a gate? Does it resemble what you’ve drawn?
I’m wondering how your gate would open if it were real. Is it a two-door gate that somehow opens in the middle or is it a single gate that opens from the side? It just seems a bit structurally unsound and unusual for either. So why is this important? I’m not sure that it is, but since it was one of the first things that crossed my mind, I’m wondering if others will wonder similar things about the gate. If so, the structure of the gate and how it works is likely an unwanted distraction.
Despite these things, I do like the concept, its simplicity and what you’ve done with it. I think it’s just a matter of refining what you have. I’m having a little trouble interpreting the brief, but if the examples are things the client likes, and if the slider bars represent qualities the logo should have, I think you’re likely hitting the essentials.
