resident evil 5 executioner WIP / my first comic convention

Hey guys, im new to building costumes/props altho i have started the odd thing but never finished, i started working on the resident evil 5 executioner for my first, its not 100% accurate, but you get the idea!!!
also i was wandering your opinion on the work so far, and, im going to my first comic book convention and am really excited so i thought id go all out and build this costume for it, (executioner) there is costume competition at the comicon and im thinking of going in for it, but i was wanting to know from you guys, if you think it would be worth entering with this first build, hopefully will have pics of it finished very soon!!! your comments/advice will be much appreciated
