looks great cept for the left side of the planet. it is kinda hard to see the edges. maybe lighten or darken bg? EDIT: also im not sure if you meant for the planet to be slightly transparent... but it kinda is in the middle.
Yes the left side was suppose to be kind the planet's turn as for the transparent part i don't see what your saying. the middle is just darker possibly like an ocean or something. i might darken the left side a little more later.
just like speckles that seem to be stars. i highlighted a few major ones. to me the white specks look like stars.
