This is a very nice poster with lots if interesting information!
My general comment is that this will be presented to a vide audience of physicists who are not necessarily familiar with the ATLAS muon detection. I think non-experts will struggle with some parts because they are very technical and contain a lot of acronyms and jargon. Think about whether you really need to mention all acronyms. If yes, it would be good to define and explain them. For example, the FELIX chip was mentioned several times but never introduced I believe.
Indeed, using your mouse pointer to guide the audience was very useful and the zoom-in feature also helped a lot, so keep using that!
Further comments about specific sections below.
New Small Wheel
-----------
Not all audience will be familiar with the LHC vs HL-LHC specifications. Perhaps it is worth pointing out the difference in the instantaneous luminosity so that the audience will have a better feeling of the scale of the problem.
The "Micromegas" detector is mentioned here but never defined or talked about later.
sTGC Muon Detector
-----------
Perhaps mark the 1.8mm and 3.2mm pitch in the picture below.
