Comments round 2:
Space Yoshi X: The Mushroom Kingdom text looks bad and is spelled wrong, does not include new URL
Zeus Koopa: Okay, but I don't like the font or colors of the main text
mariofan 7: Does not include new URL
DrewK #1: Shift the text over so that Toad and Mario have even spacing around them... have you considered a very slight shadow behind the text? It's got potential
AV-Cables #1: Too bright?
AV-Cables #2: Bad spacing
AV-Cables #3: I like the font style, but I don't like the SSS sprites.
AV-Cables #5: Motto is nearly unreadable
AV-Cables general: Bit-ness isn't important anymore so I don't care for the tagline. You're joking about the "128-bit karts" right? That doesn't even make any sense.
Super Dino Yoshi #5: Style is nice, but I don't like FLUDD and there's too much space around Mario
Super Dino Yoshi #6: Okay what is with the nonsensical taglines?
Super Dino Yoshi #7,#8,#9: Animation isn't worth the bandwidth; 1 loop isn't good since you can miss it, and multiloop isn't good unless you time it properly
aD-aX: I definitely like the 3D text... maybe make the star smaller, get rid of the "the" and ".net" and put the whole URL below it and use a different Mario
Brien DeRosa (GMail): TMK looks crappy and the banner is kinda empty, but I do like the tagline idea
Mr. Mime (GMail): Stretched text looks bad.. floating Bob-omb...
Double D (GMail): Bad antialiasing on Mario, bad text spacing, don't like the colors
nintendoexpert89 #2: Disembodied heads are odd... banner is just too... plain
Ian #3 (GMail): Pretty good, might try to make the text like our current header so that the outline is even
Ian #4 (GMail): Still don't like the green blob
Ian #6 (GMail): Pretty good, might combine some of the ideas from #3
Ian (general) (GMail): Might try a different motto, Deezer also noted that the huge amount of red and green use makes it look like Christmas
