Simple, short and just not funny

Firstly, Newgrounds really shouldn't be a place to submit early flashes, most reviewers here don't actually help.

My Criticisms:
- The art - It's good to know that you can draw a few simple figures that aren't sticks, that's a good start. If you keep at it, I hope that your drawing will improve and you will be able to create more complex animations
- The narrative - Sure a guy telling a talking horse to move is original but it was too simple to be compelling.
- Any comic factor - If this was meant to be funny, it wasn't, to be brutally honest. Random senseless violence may be funny to a minority but in your flash, it wasn't even done well.
- The sound - For a first flash, the quality of the dialogue is relatively good but at the same time it is very flawed. I could hear the microphone hit something just before the horse does his lines and again while he delivers them. Also, I realized that there also wasn't any sound effects for the rock crushing the guy which I found wuite upsetting.

Overall
Although heavily flawed, you are right in saying that everyone has to start somewhere, but you should stay away from submitting flashes of this quality to newgrounds until you improve. Good luck and don't give up.

wtf!

This was really random. I just want to know why you did it
