Try to incorporate the gun/prop into a lot of your poses. I hate when cosplayers have amazing props but they stretch out their arm away from themeselves while holding it. Try a lot of canon poses she makes, whatever you do, please don't do the overdone "Lets place the gun between my legs while I'm on my knees holding the barrel" Pose. It's over done and gets annoying...Try looking like she's taking a break, have the gun propped on your arm and lean against the wall. Look like you've just taken out somebody with the biggest grin on your face, and don't worry about trying out facial expressions in the mirror! Pose, learn how to walk around with the wig and see if you can create in-motion pictures.
Some of the best things to remember though, is not to bundle up. Stretch out your neck when you make pictures, arch you back up and head held high. Most importantly; have fun!
