This is very impressive work and it is great that you are presenting it at the APS meeting! 

In some places it was hard to follow because I could not link your spoken words to the text in the poster very well. I have a few suggestions that you can consider:
- If given virtually: zoom-in to the part you are presenting
- If given virtually: guide the audience with a mouse pointer over the parts that you are currently talking about
- Make it clear when you are switching between the sections (e.g. I could not tell when you switched between Abstract / Objectives and Results / Next Steps)
- Use bullet points instead of whole sentences in Abstract and Next Steps sections

Other more specific comments

You say that you want to implement a new L1 trigger. However, this is not clearly stated in the poster. Perhaps you can rephrase the "Document trigger and analysis cut flow for use at ATLAS" bullet a bit? Implementing a new trigger is really a big task and a great achievement, so it is worth pointing that out more clearly.

Is the placement of the feynman diagram optimal? It seems like having it in the abstract section would be better because you talk about ggF production and dark photons already there.
