I think the OP just wanted us to help him with the background. Not the overall image. OP the curvy lines are brushes that you can download is one option but the the 2nd option is to download a brush set called wavey/flourish brush set is the other. The flowery image you can make with any pic I think. Sorry If I wasnt that helpfull.
for the left part i would suggest removing everything but site name, for the right part i would suggest changing the color of the mobile phone to white or black Good Luck
sphere 1 is correct.. .indeed those are brushes.. .and you can download them.. .but if you want, you can also create them.. .i usually use adobe illustrator or photoshop.. .
hi, the flower image is a brush which you can download and to creat green background you can take a layer and give it green color like that then take a new layer and select its size as just like first then give it white background then cut it through elliptical marquee tool and then decrease its opacity and then take one more layer up on it cut it in your desired shape and adjust its opacity and you can make more layers just like this it is very easy to do.
Here is the solid answer for you: Use a Green Wallpaper as background of banner, find this in google!! And nest attach a layer of your company logo, your relevant images, and put your relevant text, keep them at their nice position by moving here and there!! Use styles to give these object some nice look!! And outcome will be more better then current one!!
