After you mix sounds good to you (all levels, db, volume are in proportionate volume) Eq it, then try a compressor, then you can use an additive limiter, or just a limiter. You can eq and compress the vocals on a separate audio track. You can eq and compress the over all mix, the limiter should be on your master fader, or in this case use a limiter on you final mix. The limiter will raise the audi to a higher ceiling giving it an overall loudness, without clipping, you can set the threshold so you have headroom just under 0dB.

if confusing i’ll check back later
