p good start for a track! you got nice basic principles of trap down, could elevate it with some mixing and mastering, as well as messing with the fx to make the track more interesting (examples could be like 808 slides, panned synths, changing the melodies and layering synths)
well, you'll learn these along the way! just like i did, watch some youtube videos and tutorials to get you started! good luck on ur journey in audiotool :D
