Hey there Doodles, first off I really like your work - it is subtle yet striking.
Your text certainly isn't awful, but I think you need to introduce some more fonts into your collection. There's maybe a little too much use of Trajan Pro and Papyrus, bring in some cool new typefaces and your banners will no doubt improve. I can't really criticise beyond that to be honest, I struggle with text often too - we're only just starting to learn about it at Uni.
Also try playing around with the Motion Blur filter on your text (or a duplicate layer), I've found it sometimes completes an image.
Your Bane banner is sweet by the way, after watching the film I made my own as a tribute lol:
Out of interest how do you get that blocky sort of effect on your backgrounds? Keep the good stuff coming!
Peace \,,/
