Hello.
I see you're quite new with iconmaking, i have to tell you this.
It's very vissible you haven't lay down more than 10 minutes to get this result, on all of your icons.
You got to make your icons insane !
So it's shown you've put your brain realy in to this.
I also see you've created 3 icons in the same time, very simulair to each other though, wait for 1 to be approved and then make others if requested.
You should also draw by hand alot, it will often increase your drawing skills at your computer.
So, lay down much more work to your icons.
And think twice before putting them out, "Would i use this icon in my map, or is it too simple maybe" ?
Good Luck Increasing Your Results, ON ALL OF THESE ICONS.
