Ok, first, I added a black outline to the bug's mouth and scaled it down a bit. That looks good now.
The line thickness around the different characters doesn't really bother me. So that's fine as is.
Blanka, I plan on sending this to mamemarquees.com to have them print it off for me, so I won't be doing any printing myself.
Now for the bad news...
As I said before I'm new to this, so I wasn't really sure what CMYK and RGB were. My document WAS in RGB before. I asked a guy at work and he said that it needs to be in CMYK to print it. I changed the color type of my document to CMYK and it seems to have messed it all up. First, it changed the colors, albeit slightly. I've tried to change them back to the other colors, but haven't got it right quite yet. But the biggest problem is that some of the lines of my picture are not as clear as they used to be. If you look at the newly attached document you will see like a weird white line around the blue parts of Mario. The black circle around the end of the tube is also much less smooth. It looked amazing before and now it looks horrible.
#1, can I get it to use the same colors as before even though it's now CMYK?
#2, is this all a lost cause because everything is all weird shaped now? Or is there some way to fix this?
Help please, I'm really scared my document is worthless now...
