Awesome work! Very well put together. If I may offer a couple of points to take things up a notch -
- Your kit looks great as-is but weathering it would take it to the next level. Especially on the blaster - it still looks pretty plasticky, get a few washes and some silver highlights on that thing and it'll really sell.
- This is something I'm working on myself but before your next con, practice some poses in a full-length mirror or take a video of yourself. You'll feel silly but having a couple of cool poses to throw when taking pictures will make a huge difference in how your costume is presented.
Again, your kit looks great! Excellent work. What are your next plans for it?
