Will my first base survive horde night?

My walls are made of tier two flagstone, with the doors being double-layered hard metal upgraded to tier 3 or 4 (when rebar is shown). I have a balcony I can snipe down on zombies with and only two openings zombies can get into-- both of which have two gas barrels on them that I can explode if zombies start to pile up on those choke points. I'm still working on my spikes, but am planning to double layer my walls (tier two flagstone) as well as my spikes.

So here's my question. Will this base survive the 7th day horde, or do I need to rework it?
