Actually, rules are made for the reputation of the comics to be clean. In my opinion, everyone should share a common or maybe an almost-same type of creating the comic to keep them from having a mish-mosh of different styles and styles that aren't just good enough to fit for the standing majority. For instance, polandball wasn't made to be perfect and using the circle tool is too effortless to look at so using the real tools in drawing that is available in Paint or whatever photo app you have can spice-up the creativity of yourself, it may seem hard but seeing something you worked hard on is pretty much fine. The majority of polandball creators on the internet prefer to use this because it makes things look organized (e.g. having a plot with a sense, the right font [I mean comic sans... really?], right colors, etc. etc (If you go to polandball in Reddit, you'll see what I mean). Again, rules weren't born together with polandball, they're just there to keep things in order I mean who doesn't like to see things in order? Still, it's your decision to abide the rules or not since this site is not as strict as the fascist mods in Reddit. Although we seemed forcing, a little criticism and informing won't hurt because I (or maybe "we") have already been there.
Ok what you say make sense, but i have to disagree with your opinion about styles of making comics. I think some people are not as talented as others, and besides that i think different styles make this whole place more interesting and it would be boring if everything was made the same way. But thats just my opinion.
