First, could you at least TYPE with proper english? Or type actually words?
Second, if you want people to just come here and say, "LOL! TH15 COMIC IS DA BAST!" then you came to the wrong place. By posting your comics here, you are asking for help on your comic. If you don't want help, then don't post you shitty comic here. We got too much of that.
As for your comic, let me brake it down.
Plot: There is none, and but not having a plot is not the problem. It would be a problem if you were going for a on going story but I don't you think you are. The problem is that you have no goddamn punchline. And the want-to-be jokes are as old as my grandmother. Get better jokes. And avoid the "We know were in a comic thing" it's stupid, old, and cliched.
Sprites: I'm going to skip this part since I hate fuisons but have no reason to. Except maybe the fact you tried to pass off a bulbasaur with two legs with a rock. That's just stupid. Try Edits, or Scratch sprites (Good scratch sprites), they first will look better and second will have more poses then just standing here. In battle Pokemon Sprites are not a good use in sprite comics. There are so many game sprites out there, use on with more then one pose.
Textboxes: Actual textboxes would be better, but no problems here.
Grammer and Spelling: You spelled (Dam + n) wrong. You also don't know how to use capitilization apparently. After a "." or "?" or "!", the next letter is capitilzed. "I" is special because if you saying "I" or "I'm" the "I" is capitalized. (There is an " ' " in I'm.) Also, you seem to not have a good grasp on commas. A comma is put there in a sentence to take a breather in a sentence but not to end it. What you said in the comic, "DAM, I FORGOT, ARRRGH!" is take a comma and destroying it. What it should have said is, "DAMN, I FORGOT! ARRRGH!"
Taking that sentence but changing the subject. Has ANYONE ever said "Wtf" in real life? I haven't heard anyone say that, unless they are mimicing chat speak on purpose. If you sent on a volcano with explaination, would you say, "wtf?" Anyway, on what I was saying about that sentence. Why do all your character say extra things then what people would actually say out load? "Oh no! I have fallen down a well head first and I'm going to bre-CRACK!" no would ever said that if they fell in a well. They would say, "AHHHHHHHHHHHHHHHHH!" No one would say, "I'm going to cut the rope when you bungie jump." They may say it in there heads but not out load. Another reason to use textboxes, can switch from talk to thought.
Effect: Bad. Lines to show he fell, cheap. Show him falling in air, better.
When the guy gets hit by the bungie jumper coming back up is also cheap and bad. If you got hurt, one you would show yourself being hurt and two, you would not get flatter.
