Just remember this is meant to help others who are trying to get their efforts right first time without knowing where to start.
The spare radio aerial holders (Long plastic tubes on the rear flanks of your Tiger) The Tiger 1 had one (Except for the Command Tiger which had a multitude of aerials and an additional spare aerial holder across the rear plate,) and it was on the right flank (All left and right is from the drivers position looking forward) and the real one was not flush but elevated by a few MMs, It is easy to remove the wrongun, Get the blade of a craftknife under the end and gently slice along its length pulling it up as you go, It will peel off,
Turret mounted Spare tracks, The most that were fitted was 7, 3 on the escape hatch side 4 on the pistol port side, No problem with them on the front glascis although it was not an official mod indeed the German Tank industry carried out research into the effectiveness of spare tracks being used as added armour, They discovered it was not only not effective but actually potentially weakened the inbuilt armour,
Headlights, You are using Heng Longs idea of the Tigers Headlights and they are horrible

but it is less of a problem than you might suppose because the number and placement of them varied across the years of its manufacture and often were removed by the crew before going into combat(The Tank Museums Tiger 1 131 was captured with its headlights absent)
I love the armoured barreled Cupola mounted MG34 So often the drilled barrel is seen on models,
The paint job is really good although I avoid decals wherever possible and use stencils which of course is how it was done on the real thing. If you check the Forum you can find out more about stencils (Supplier),
I am desperately hoping you are taking these comments in the positive way in which I intend them, Overall it is a very good example of a Tiger 1 early.
