It's not bad, but there wasn't that much of a point to it.
I like your background at the start of the movie.
The overall movie could use a bit more color in places since a lot of the drawings were black outlines.
A lot of the color was mostly white with a few exceptions in areas such as lasers, eye pupils and others.
You made the common mistake of drawing your city as a series of squares with windows.
An actual city is full of complex structures of a variety of shapes.
A city is actually very hard to draw.
I like your many uses of camera angles and you used a few smear frames at some point.
The guy falling down used smear frames when his hands were going crazy.
The jewel was created using the gradient feature of flash.
I hope this review gives you plenty of useful information for future improvement.
Best of luck with your new movies.
for your first attempt it's not that bad. You should make more.
