Try this:
If you have the .PSD, open it up. Select the text, then go onto Layer > Layer Style > Blending options, and play around with all the settings, just to suit your needs. You can even change the opacity (Transparency) from 0& to 100%, play around with that and see what happens too. As well, if you have those brushes on a different layer (Wasn't placed on the black background) do the same thing you did to the text, and see where that goes.
Also try adding a border as well. To do it, you must select the whole document, and then go onto Edit > Stroke. Make play around with the settings, and you're done (Make sure you've created a new layer if you want this to work, and make sure that the stroke is "Inside", so you can see the border. Play around the with the Borders px and you should come to something good.
Oh and listen to Llama, making brushes is way better than getting them off the net, I do it sometimes, and I have a shit load of custom made brushes, play around with photoshop and create some brushes, it does sound hard, but trust me, much more fun and gives you a whole better stance when it comes photoshop. You'll also find it much more easier each time you do it. Of course, if you don't like doing that, then fine - You can use brushes off the net, but make sure you've positioned them correctly, like my sig. I've used most brushes on my sig, but when it comes to the splash effect, I use simple brushes (The ones which are default and come with photoshop and place it anywhere, then use the smudge tool, now it looks awesome.
Try this stuff out, you can develop such awesome work from it, it does take time, but I believe it's worth doing. I've spent up to 2 years on using PS, and it's already a bloody brilliant software to use, it will take time like I said, but this software can completely make life easier when it comes to general graphics/Art work.
Hope this helps mate.
