I think these are very nice,and different to other things that we usually see here. It's a very nice idea. I think I prefer the first one the best,as the colours and style of it look rather lovely,and the text is very nice. But all three are good,and as I said,interestingly different,which makes them even more exciting to look at. Very nice work deary~
I dislike the circle brushes. Maybe if you made them blend more, changing the layer mode and/or opacity, I could appreciate it, but... I like the last one the most. Stick with that type of font, lower opacities or add overlays (repeats of the same layer with different settings) to blend it, and you will have a nice piece of work. Do you play with layer opacity often? The reverse RGB on the first two really throws it off. Stick with similar colors if you can. You will rarely go wrong with a matching palette.
I liked the first one, the letters are wonderful and the colors are different, making it looks like more than the third one which is all blue, though the three are very nice.
