I need a Professional Sound

Hi I'm Christian, 25 years old, actually my job isn't in music industry, but I'm trying to produce my own trap beat, workin' with Logic Pro. I'm a fast lerner, I've met some teacher and had some lesson; they thought me some professionale tips, but now I see I'm not reaching my goal: how to make the right formula to have a professional sound. How could I choose the right sound to have a professional impact? My drum is 'muffled'...Could you help me? Many thanks, Christian
