Looks fantastic!! Next time you do it, take the extra 30 mins and do a clay-bar as well, really makes the wax go on smooth and makes the color POP!
Kinda leery about trying to clay myself. I'm worried about screwing my paint.
Looking at your engine, it looks pretty clean, but try these things out. The first is a degreaser, which you spray on a warm (but not hot) engine and hose off. Either dry it using an air compressor, or go for a short drive to get it dry. Then use the second product to get it nice and shiny. Its safe for all parts (keep it away from the exterior, though) and makes it easier to clean up later down the road.
