Resistor,
A great looking Tiger!
To make it look better eschew Bandai/Fuman's tools, they are awful. Go to your model railroad supplier and buy O scale--1/48--tools, like these:

These are from O scale model railroad maker Berkshire Valley. White metal, I left one unprimed. The tan pieces are from the Bandai 1/48 Tiger. This is a good example of hobby-crossover.
Prior comments about paint scheme, weathering, etc. are good advice. I have a nit-picky trivia that many Tiger fans miss. All of the Porsche turreted Tigers wore zimmerit. A Royal Tiger's royal pain in 1/48

I did so with mine:
1/48 Zimmerit Tiger II Decals? At the National Model Railroader Assoc. national convention week before last, I talked to the Micro Scale rep who told me they would soon reprint 1/48 AFV decals

Otherwise, Gasoline, etc., are good, too.
I await seeing your finished tank, with or without our constructive critiques.
