My main suggestion is to weather stuff a little; your pants look fresh off the rack, not like you've been busting out of prison and shooting people XD Are they cotton or synthetic? If they're cotton you can squirt some black/brown rit dye on them with a spray bottle, if they're polyester or nylon you can do the same thing with diluted acrylic paint. Here's
some more stuff on weathering. While you're at it, you can grab a seam ripper and remove the cargo pocket on your right leg.
The pics I've been looking at show her boots without noticable laces on the front. You might want to pick up some brown vinyl and make some half chaps
. The vinyl can be weathered by smearing diluted acrylic paint on it with a paper towel; it'll really stand out if you apply it over any seams or topstitching on the finished product. Also, you can make the half chaps higher than the tops of your boots, so your pants stay tucked into them
