G4 Sweetie Belle's real cutie mark as of Series 5, Episode 18 and later. I've made the background of the shield more transparent to allow the individual part to stand out more, not an uncommon tweak in fanart TBH.
This cutie mark is a body element, meaning that it (+) appears under clothing and underwear, but it (-) picks up the HSL tint colour from the "Her Skin" sliders.
Original .swf template and code is by @dantethedarkprince. The cutie mark shapes are by Parcly Taxel, Princess of Science, optimized for Flash, tweaked, and repacked by me.Code:charName:Sweetie Belle;mood:Happy;bodyScale:1;arms:onhislegs,onhislegs;throatResist:50;hair:sdchan,1,1;iris:wide,97,151,92,1;breasts:70;skin:pale;nose:normal;ear:normal;lipstick:0,206,154,186,0.071;eyeshadow:134,100,145,0.392;sclera:255,255,255,1;blush:255,48,109,0.157;freckles:60,24,24,0.8,0;mascara:0,0,0,1,30;nailpolish:0,0,0,0;eyebrow:normal,246,184,210,0.502,120,90,137,0.502;hairhsl:0,1,1,1;skinhsl:0,0.49,1.09,1.09;hisskinhsl:62,0.57,1.04,1.74;bg:1;hisBody:male;hisPenis:0,0.98,0.985077720207254;balls:1,0.796;hisSkin:1;hisTop:shirt,133,24,102,1;hisBottoms:slacks,35,0,39,1;hisFootwear:none,0,0,0,1;collar:none,0,0,0,1,0,0,0,1;cuffs:none,0,0,0,1,0,0,0,1;gag:none,0,0,0,1;panties:none,0,0,0,1;top:none,255,255,255,1;armwear:none,0,0,0,1;legwear:none,255,255,255,0.8,0,0,0,1;footwear:none,255,255,255,1,0,0,0,1;eyewear:none,0,0,0,1;headwear:none,0,0,0,1,0,0,0,1;tonguePiercing:none,183,187,195,1;herTan:none,0;customHair:SweetieBelleHair.png;swfMod:MLP-Cutie-Mark-CMC-S5-Sweetie-Belle-Skin.swf,1;swfMod:MLP Tails - Sweetie Belle.swf,1
