What we mean is that you should explain why this is better than the other one...basically just list the pro's and cons' in your opinion. Don't just say what is good, also say what is bad in other words Like for example only, I'm not voting on this.
Entry 1 has good colors and text and nice overall. However the jellyfish on the left side is distracting and the outer glow on the zoid is distracting. Nice concept too but it could have been executed better.
Entry 2 has a nice concept also but he/she left too many space out whereas it could have been used for effects and such. the lens flare is distracting so as the text too. However the blur of the sides of the gear is kinda appealing and the brush technique behind the gears is nice. BG is kinda plain though.
