Missing hits?

I'm sure there's a name for it, but I appear to be missing hits due to tracking, and I'm curious as to the solution for this. Hold my hands out further from my face? Hit the blocks sooner?

I notice it most on my right hand side when the blocks are higher than waist level. I've tried adjusting my swing, standing a bit further back on the platform, but I still miss.

It's frustrating, because I'm new at this but I can certainly do the songs no problem that I'm missing on, preventing a perfect combo.
