Hello from the critique club

An appealing image that contributes to the open challenge.

A very competent astrophotography shot which judging from your very helpful comments took a lot of careful execution and presumably patience which has been well rewarded with this excellent image. Iím not sure thereís much I can add in terms of critique you obviously have the skills and presented to the right audience Iím sure this would receive the acclaim it deserves.
