Okay, then. The only issue that I see is that it breaks the rules. I mean, sure, for some reason, circle tool and line tool are apparently allowed on this site, but nonetheless, they still break the polandball rules. What I think this site doesn't allow is the mouth and those eyes. Countryballs don't have mouths, and have pure white eyes without pupils and have black outlines. I understand that it is hard to draw circles with only a mouse, but that is the rules, and what I do. I did start of as somewhat a bad "artist" and still am. What I am saying is that try to not break the rules, as they make your art like better, or something. Circle, line and other tools make it seem like you didn't put any effort at all to this. I'm sorry to say this, but you asked me to critique it after all. I am not mad, or that I hate this, but I am just sharing my thoughts. You are free to do any style you please, but if I we're you, I would abide by the rules, even if it is hard. This goes to other people using circle and line tools. Good luck if you will draw some more! I'm just going to wait for the hate on me saying this now.
This was my first serious drawing, to show you how bad I was, but still put effort on it, and didn't use circle tool or line tool at all. http://countryballs.net/_nw/43/63099690.png or http://countryballs.net/news/the_tower/2017-11-13-4322
