Superb resolution, and perhaps more importantly, you've got the colours bang on. There's a bright B9 class star about half way to 4 o'clock which you show as blue, and a bright K0 class atar most of the way to 5 o'clock which you correctly show as yellow. There are those who would have both of those stars blue, so the whole 10 billion year old cluster is bright blue, a physical impossibility.
And ... you've got North at the top. That really helps people compare. For example, there's that lovely "southern cross" asterism (again with perfect beautiful colour) at the three o'clock edge of the cluster, which is easy to spot in your image.
