Flame painting help

[03VibeGT6Spd]

Friday, I decide to paint my 3 year old Daughter's helmet.I was mostly egg shell white with massive scratchs all over, after sanding it down for hours I started laying paint and ended up with this.I looks better inperson then in the picture.After doing this, I decide are scooter needs some help also.I'm thinking about adding some flames around the front fender, But I need some graphics because I'm not much of an artist.Can anyone point me somewhere to find some simple flame work.I'm planing on using the same colors yellow and red.
