Good clear video. Little slow start.
Shame there's no audio, but understand.
Some comments anyway:
- Music copyrighted? Then don't use it.
- Music NOT copyrighted? Then don't use it ..... < does not help to add any credibility, nor enjoyment for the viewer.
- When still want to add music try to mind the following: keep volume low, keep tempo of music low (or in-sync with content)
- maybe text lay-over instead of spoken audio? I always find this clarifying and prefer it over none.
keep it up.
