If anyone here is being rude, it's you. Saying something looks weird, even on a practice doodle, isn't a bad thing to do. In fact, it's helpful, especially if you can explain why it looks weird. People here, as a general rule of thumb, enjoy critique so they can improve. For example:
The Spy here looks great to me. The only thing that I can really say is it looks like he doesn't have pupils, which when sitting next to others that do, looks off.
The Soldier, while overall looks nice, I still can't get past the weird, dark splotches where his other eye should be. I get there wasn't a whole lot of room there, but it just stands out, especially since the dark-colored splotches are right up against his much more lightly colored nose. The contrast is a bit jarring, to me.
The Sniper is the one that I think looks the strangest. Though I really like the way his glasses are colored, that's great. It's just the way his eyes in particular are positioned, it gives me the feeling that I'm looking at a plastic doll. I think part of it is also the completely neutral, blank expression. With the other two here, Spy looks sort of pensive, Soldier looks bored, but Sniper doesn't appear to have any emotion at all. I think he would look a bit better if his eyes were just slightly more closed, like half-lidded, to make him look like he was bored or tired instead of the blank, doll-like face.
So please, don't try to pick a fight when someone says something less than positive about someone else's artwork. If anything, >>8313 is trying to help "the picasso in our fandom," as you put it, to get even better. Isn't that a good thing?
