Not the worst, but far from the best. Most new mappers put the wrong tempo (you put 120 bpm instead of 84, which is the song's BPM) and then make patterns which don't make sense at all. Most sliders and circles don't follow the rhythm and you didn't put a circle with the "New Combo" option anywhere. It is also worth mentioning variation of Slider Velocity, which you did not apply on your map. There's also random difficulty spikes, which, if applied correctly, is rankable. On this beatmap, difficulty spikes don't have an excuse since there's no signs of noticeable difference of intensity during the song, since, most difficulty spikes are caused by difference of intensity of the song.
You get better eventually. It may take some weeks, months, or years. If you do not give up, you will eventually get there. Also worth mentioning that you at least tried to map, instead of just requesting someone to beatmap a specific song for them in the Beatmap Projects forum.
