First time waxing, how bad did I mess up?

Bought a waxing kit and wanted to try doing it myself, but think I used too much wax

Scraped for a long time and brushed for a long time was well but there is still white wax residue on board.

Anything I can do to fix this? More scraping? Or will it resolve itself after a day of riding?

Please help! First time and my board is a mess compared to when I have professionals wax it
