Best Thing would be replacing the Sun too, use a Lense Flare for that. You can even make it yellow with placing a new empty Layer above it, then use the soft yellow Brush to give it some Colours.
"Who is it doing this synthetic type of alpha beta psychedelic funkin'?"
I don't think the liner blends in with the background much, if I were you I'd just take it out completely or enlarge it and gaussian blur the edges for around 5px at 45 degrees or something so it has motion.
But that's just me.
edit: schlurb, give the guy some credit for his effort. You know how long it takes for someone to master the secrets of Photoshop.
