I'd give you about a 4 out of 10. That translates to, "While I didn't think the comics were funny, they were at least readable and didn't cause me to hate the author."
You've got the rhythm down--you just need better jokes. Keep trying.
I love the Safegay one.
The rest- well, randomness only goes so far. It's seen too often on Stripcreator comics- what you need is something to stick you out from the rest. You should continue on the lines of the Safegay guy. Maybe give him a name. ;)
