ok here we go
first off nice scene but here's what needs critique
1. the glare off the sun is too thick, requires a tone down
2. there should be flaring off the surface, though good texture it lacks the chaos of a true sun
3. the outerspace seems dull but im glad you added in fog instead of just plainly doting a black backround, good points for that.
other than that its pretty decent so 7 for you
