CnC man thats a long time ago for me ,but i will give it a shot
background is nice ,but it could use a bit more action init
try to blend the render a bit into the background
text: cuz the sig got some negative space you should resize and replace the text to a better location
what i would do with the text...>>
take 2 colours from the render 1 for heart the other for keeper
make the first letters from the words bigger then the rest ,add a dropshadow
play with the opacity of the layers untill it looks good and fits the sig and fills up the negative space
let me know when you need help
kep up the cool work m8
