After being in so many contests I learned this:
-If judges are not skilled with experience people, don't bother
-If the rules ona contest are too weird and over written, draw porn, orgy the better, you don't even have to draw well or color well, doesn't matter, you'll always win
-on a deviantart organized contest, the more animu you draw the better UNLESS you're godly skilled that hurts, then you'll win too...or not
-If you wanna increase the win factor, then research bout the judges, their favs gallery, link the names and nick. This increases your chances a 30% more but won't assure you a winning, unless of course, you draw porn.
-So if the judges are ex friends or enemies, don't even try hard, not worth it.
Lil persona experience: on a contest her in my country 2 judges that happens to be here on da, really n00bish people, placed me in a lower place coz they hated me for the visits you people throw me, who cares right? not even using my deviantart lately anyway. There's a weird thing bout egos on my country i'll never get to understand, super weird effed people.
-If you've to draw boys and girls, ALWAYS choose girls, unless you make a porn, then add 2 girls and only ONE basic guy, you don't need to know how to draw a boy anyway
-If you lose becuase there was someone better, learn form it and get better, if you lose coz it was a popularity contest,a 2skill doesn't matter", or a "show me your tits" contest then you've all the right to get pissed
-Judges put the rules, true you don't have the right to say anything if rules are crystal clear, but when those are tricky man...burn them in hades, I support you
-Always use the smallest chance to force you to improve, a contest or a commission can be a nice way so seize the moments
-DON'T use traced materials for contest, you usually get more feedback for it and you can get more easily caught, if you trace to learn, then DON'T POST IT ANYWHERE! and don't lie, we'll get you
-Always mind your own business, keep focused, adn yeah, there are always crappy art on contest, but you know what? they still have a chance to win because judges are after all...human
Hope this is worth of something for someone, also taking off my chest some shit I've been seeing lately that pisses me off
I still advice you not to draw porn all the time, coz it makes your brain numb and gets you propense to trace from photos and get kicked out from home
Be good, and let me know if any of this os worth for you, and for the haters, suck it!
