Just listened to these and tbh none sound like grime no offence they just sound like rap/trap beats especially the drum patterns the drum patterns you used are typical trap patterns I know some of the new school grime beat have elements of trap in them bnut you can still tell its grime this doesn't have that. also work on your mixing a lil more the beats sound muddy and on the 2nd beat you let the 808 take control over most the beat if your gonna do that I say create different interesting 808 patterns.
these beats are smooth! im really liking the melodies. id suggest adding a bit more variation but overall i think these beats sound solid.
