xSetrox, since you seem to have a lot of misconceptions and are confused, I will clear things up for you.
1) In reference to the text being tiny, Zealot said nothing about it being hard to read. He said the proportions of the text compared to the sushi rolls is not that great (in his opinion and mine). Text can be a little bigger. It has nothing to do with readability, but more so with proportions.
2) Your image is square, that is correct. This isn't a "so!!!!!". It's a header for a webpage, therefore it would benefit from being rectangular in regards that the width stretches over said portion of the webpage well enough over the height.
3) If someone want's a high quality image, again saying "so!!!!" in regards to it being blurry is flat out handicapped. Do you hire a carpenter to lay down hard wood floors for your house, then let him off the hook when he makes them crooked and says "so, you can clearly tell it's hard wood floors!".
4) You did take too long, and someone better came along. This is a basic life rule.
If graphic design is your thing, well then take these with you and learn some more, practice, do better. If it is not, which I believe to be the case considering how you just blow off important aspects like they are nothing, then you should either refrain from doing so as a whole, or take criticism better. You just seem upset that someone else got the prize. Don't worry, it's just a $5 stuffty steam game.
Now, I also apologize for having to rant about you like this, but really, it's nothing personal.
