Well, to be honest every bit of it needs a repaint to be accurate. Its ROTJ SE basically, loooks like yuor missing shin tools....one of the knee darts is not the pointed one so thats wrong, chest armor needs to be mounted better velcro doesnt work very well for armor honestly, need more ammo pouches if you want it to be SE, or repaint the helmet to ROTJ, Flightsuit needs to be slightly lighter color grey, chest diamond looks 1 dimentional not thick like the armor...should be same thickness no cutout its an indentation in the middle of it...that one looks cutout. Need a proper neck seal, there may be more things but the pics are kinda small to see every detail of the guants and such. To be honest about aproval with decals you might get approved, I dont know how picky the approval process is...If I was the approving official, I would tell you all of these things though. From here Ill tell you the truth as far as what is not screen accurate at all...The Jetpack you have is an older less accurate in shape version I think mark bradley (correct me if Im wrong please) its something you may want to change in the future to a MOW or RS propmasters or Fettpride. The Helmet Id upgrade to a Fettpride premium or GMH depending on how large your head is/taste...the armor is kinda thin looking shoulders seem like theyre very thin they should look thicker then flat metal...Id look at FP or RKD (redkraytdragon) for the armor...both do ROTJ armor and guants...not sure what the guants look like up close but they have the apperance of being decent...blaster looks like it should be upgraded or refurbished with newer more accurate parts if it has a webley as a base....i dunno from the pics I cant tell whats going on with it. Cant see the girthbelt to well so can t tell you anything about it, but depending on the straping in the back it may be wrong as well...cant see side pouches so the colors may be off for SE. This is alot of stuff you may not even want to bother with just food for thought as far as making it better over all..
I think you can make it acceptable according to the 501st and I think thats what your aiming for off the bat...good luck with it.
