I meant that the concept art you used looks like they are old and the colours fading.
Really nice banners.
Can I maybe put on a request?
If so tyvm.
They look nice, I like the shaymin one xD but They look very bright maybe you should lower the brightness :] And the text seems doesn't match. Maybe you should take a little tutorials in text. :]
The main thing I don't like is the background, it looks like you just slapped a render onto it and added some text. (Also some blend layers I believe, and these are actually relatively well-executed.) The stuff you choose is also really busy, and your renders are often lq/waaaay too big. You could be the best artist in the world, and your tag would still look bad if you had a bad render. I do like your typography, but it would be better without the gradient overlay. =/
