Not bad for a initial edit.

id suggest to try a generic edits,and keep doing generic edits until you think you got enought skill for some real regular edit.
generic i mean trap songs,default replays,simple/boring CC(Abreviation for Color Correction,i have done a VFX Breakdown on my channel showing steps of CC,color curves are the best imo)

Try to sync more the replays with the song.
but i really liked that glow effect...

Record in slow motion(reduce the speed of the replays while recording) to avoid clip looks laggy

Search on youtube "how to sync in vegas/after effects",these two programs are better for making some edits.

Fuck i done a wall-of-text cnc,then browser crashed rip
