i find it way, way too dark, and as a thumb it will look black. you uploaded 2 that look identical. i'm not sure what that ring around the earth is. further you should mention what side of the world this is. most people in the area they live in - won't recognize this as anything. in the US, people expect to see america. i see your in japan so i guess it's that side. but overall, i can get the real thing at nasa for free.
and vivian is right, not many want to see your latest, as it tends to fill up the forum really fast. the critique groups we have is the best place. we aren't your buyers, so asking for critiques on everything as a form of advertisement - buyers don't come here, not directly anyway.
