IMO, fix the banner. Remove all that glossy crap in the emblem and on the background, they look like fancy drapes from 18th century.
And the colours are a bit ugly too, but that bit is preference so no offense meant.
Heraldic banners were mass produced or sown by each soldier's relatives or spouses or whatever, they were of simple fabrics with motiffs.
Just saying, some aesthetics couldn't hurt.
