I second Pnk_Panda_3's notion! You look great, but you're missing so much more. Look up more fire themed/other clothing items on tektek. You'd be surprised on what you could find. Good luck!.
I agree, you got a good base but the Magic Mountain Orb is not the best item to use for fire bending. There are some other items out there with way better fire poses in them. Try some more searching and experimenting.
