Let me list a few reason it sucks.
-I drew the exhaust (looks like crap)
-I drew the "moon" (light grey dot with smaller dark grey dots)
-Sunny side of Earth is on the dark side of the rocket
-Drew in the engine (I think)
-Badly inserted picture of earth
-Engine emits no light
-Low resolution for the rocket
-Rocket was badly pasted in
-etc.
EDIT: Just remembered I put the ship together part by park in my drawing program based on random screenshots. That's why I drew the engine (I think)
