My hat is off to anyone who can use After Effects. That's my next thing to master.
I wasn't put off at all by the color shift. Since it happened right before a visual transition, it looked like part of the effect.
I would offer these observations:
1. A faster pace would have been beneficial. Shorter is usually better for promotional pieces, especially with today's short attention spans.
2. Vary the visual effects instead of same transitions repeated with different text
3. Music transition was abrupt at :32 in. The one at 1:15 was great because you transitioned between phrases of both pieces.
That's about it.
Nice looking spot overall that I'm sure appealed to your target audience. Keep up the good work!
Hope this helps,
