Could be great!
Some helpful advice for future works.
1. Smooth out the transition between sound clips
2. Add music (Best to find something that fits the situation)
3. Again smooth the transition between 2d and 3d
4. Work on your 2d art a bit. It looked nice but proportions were a bit off.
5. Add more detail where detail is needed.
6. If your going for action you'll need alot more of it. If you want a bit of comedy then hire a writer ;D hehe.
Show alot of potential just need to be patient and put more time into your work. Do a rough draft then go over it and over it again and again and again. Then run it past some friends/strangers and ask for suggestions and if they sound good and you think you can work them in, then go ahead and implement them. Then toss it on newgrounds and i'm sure you'll hit front page ;D But remember like any story (or action clip even) you need a beginning and an end. (and alot of other stuff but those 2 are most important. So basically "Round Start" bam bam "CT's Win" or however you want it.)
