Were you trying to do a "misty tag" with the pink bg border? If so, you failed. Mainly because the tag is short, and not only that, the tag is black and white. So it doesn't fit together naturally. I would just take the pink out and leave it to what you're current signature is now.
Pretty decent, my only suggestion is making the tag is a little bit more brighter? In terms on depth so riku could blend more with the tag and not stand so much out like a sore thumb. The text could use a different font maybe, but good job.
I think you should have chosen a better 'choice of stock' to begin with. Not only that, I think it needs to blend in more. Maybe gradient map; dark red? There is so much going on in the background, I just don't even.
TEAM TRICERATOPS (DPWolf & mixt) - nice and simple.
TEAM VELOCIRAPTORS (Misty & Guardian_Soul) - It has a nice flow although, as some of the others said ; the random bubble seemed odd, and the smudging felt like a last minute "to-do". Idk, I still like it overall.
TEAM BRACHIOSAURUS (Laplace & Cody) - Too bright; focus point is way off and I can't read the text. The only best to last one that I saw.
