Wallpaper is nice,good choice of colors and nice blending there.David sig is probably your best.More than your works I love your spirit/attitude,your so damn helpful and good in nature keep that up for a lifetime.For icons,place the stock well and no need of text in them unless you feel there's a need.Go with simple but effective effects try not to overdo them,selective color would help in this.Go through tutorials on sportgfx,they're good to go with.Great luck bro,do well.
