looking pretty good so far! at 2 seconds, where you transition in from the scope to the target, I think a smooth zoom would look sick.
the next transition could use some bloom and sort of distortion to move to the next part.
make sure to sync :04-:06 correctly, and maybe adding some effects in there would help. your transitions do need a ton of work however. at :07 I can see your clip stop moving before you transition and you never want that to happen.
it's not a bad start, keep working on these and focusing on one specific subject and you'll start improving very quickly
