Constructive criticism one: In the future, only make one thread for all of your read my comic needs.
Constuctive criticism two: Pick ONE of YOUR threads and only use that for posting your comics. Do not post your comics in other people's RMDC threads. This is bad juju and everyone will hate you for it.
Constructive criticism three: Use jokes that are either new jokes you make up and not spins on old junior high material, or marginally coherent stuff. Avoid using OMG LOL I'M A CAAAAAAANIBAAAAAAAAAAAAL erm no blah blah kool in a comic, for example.
Constructive criticism four: You hate your stepdad? GREAT! Use it. You have problems with life in general? GREAT! Use them. Add a sarcastic spin and throw in a cock joke and you'll be fine.
Constructive criticism five: Posting your myspace page as your home page was a bad idea. Especially since everything is set to public. Make it private. Seriously. It's better that way.
Constructive criticism six: Read other user's comics. They will gie you some ideas and show you how to write, and spell, and stuff. Read the toprateds. Especially the toprateds. And learn to capitalize and punctuate correctly.
Good? Good. Now back to my fig newtons.
