Well...
Well, your art style is your thing, and it works for you, don't change it. You are a good writer, your slapstick is great, but you second guess yourself and that's where I have to say, you let me down... "I also was just going to keep it a silent flash with only the main music theme..." I'm sorry man, but you should have, it would have worked out better. In my opinion, which you do NOT have to respect, the sound effects took away from your good work, I found myself looking away from the main product, and wincing at the sounds. You have a good thing going, don't change it too much. Its hard to make something worthwhile, but its easy to ruin it as well. But don't let this get you down, you do good work, and I hope to see more from you in the future.
