A tween and a poor animation shorter than 1 second
Even for a trailer, this is poor. Nothing about it makes me look forward to whatever could come of it.
Nice drawing of the shop, but that's about it. This was pointless, and I hope that the real thing doesn't reflect on it.
Also, the way the cursor changes over the flash also seems pointless and just takes up filespace making it appear. Unless this flash is interactive somehow, I reckon you could lose it as a feature.
