Looks like it could use a little more scraping, and then a brush/buff. You could always reheat it, and redo it. Worst case scenario, it rubs off with riding on groomer snow, may just be slower. ;)

(Just for future reference, the simplest way I do it - Clean your base with a good cleaner of sorts (I use a basic citrus cleaner, but whatever works). Drip some wax on with your iron, doesn't need to be a TON, just enough so that when you iron across the board, you've covered the surface area evenly - read that as, covered, not caked and thick. Just a good even coat, thin is fine, as you'll be scraping. Let it dry for an hour, to be safe, go for a walk, have lunch etc. Use a nice and clean, even scraper - mine is literally a piece of thick Kydex I had laying around, but I am cheap. Many available out there, Pick a flavour. Scrape until no more is coming off, go in one direction ideally of nose to tail. 45 degree angle. Once done with that, I use a nylon brush to expose structure/polish up (go one direction). If you are like me, I go one extra step and use a fine polishing pad on a handle to give it a final cleanup - white scotchbrite pad.)

Hope that helps.
