Not it's just personal prefence.
For example: Desinger's entry combined a nice theme, with a great UI, professional, text, Interactive (Tabs), and even a SDN logo (He went above and beyond!, now for Zaros I liked his theme and user interfaces (For ores), i thing he should have put more attention to detail, added more info, maybe displayed some things in a more compact way. And finall,y alphaDeign's just had a unigue, sleek UI. He could have spent more time making the elements match the theme more.
I loved then entries, and hope to host many more Gfx competitions! ;D
