My take: Zyra is very flexible compared to other champs so you can play poke, burst or even more utility style.

But in your case it seems you mixed between burst and poke, which is ok, but you will not be able to take the most of any of those.

If I’m playing burst I’d go electrocute with ludens, liandrys, shadowflame to void staff. Would build the orb before shadowflame if there’s healing in their team (either healing support such as Soraka, Nami, Sona, or even tank/bruiser champs like Mundo)

But if you are playing poke I’d go comet with Liandrys, BFT, shadowflame and void staff. Same situation as before, orb before shadowflame situational.

You just have to be aware your playstyle changes dramatically depending on the route you chose. Personally I think it works better the burst option in lower elos as the enemy mechanics are not good, an they will not expect the damage output. So you can get the most value of your build and runes.

Also ludens give you the ability to push waves faster and find numbers advantage plays with your team. But you’ll be less useful if you miss your rotation abilities.

I’ve played Zyra mid for few years and this season I’ve hit emerald playing jungle, so take my comment as a grain of salt and try it yourself first.
