I found this pretty amusing like the text poiting saying "dinosaur!!!!!" and the part when he fell and broke the ground :P not bad for a beginners submission.
you've made quite a good start with your flash, I do think you should keep practicing, your first one isn't bad. I'll give this a respectable 6 for this.
I dont know why, but that whas very funny XD
I really liked it! It was really funny, and the music fits really well with it.
For your first attempt at flash I think it's really cool.
I just think you clean it up, and add more funny moments, I found it all a bit dull after he fell from the ravine.
But I must say, really well done for your first try.
