Wow, that opening scene was pin sharp on my laptop 4K screen, amazing detail. What are you flying to get that? How did you get such good detail in the shadow of those dark grey rocks with the sun in the background as you flew backwards? Great...
Strongly suggest Bayphoto as a pro lab, also Whitehouse in Minnesota or on the border of Wisconsin. They also offer free UPS shipping of your prints. These are Pro photographer labs and offer very high quality at reasonable prices.
You say you are happy, however, you need to tell us more. You are happy with Wallgreens quality, compared to what??? You need to tell us what you are comparing them to, otherwise, there is no validation of their quality.
Wallgreens printing in general, is absolute rubbish, if you know what quality is, of course. If you have never seen a print from a pro photo lab, then yes, you might think Wallgreens is great.
