India goes all-forward? That's...... unusual. The deck armor's good, but the side armor's pretty marginal. I suppose the idea is to engage at long range and use the ship's speed to keep out of closer engagements. Very extensive heavy AA battery.
Since I'm not a fan of the all-forward arrangement, I'd be tempted (in India's shoes) to look at something like this (it's a development of the BCs that HDW designed for Argentina and Brazil, modified to use Indian calibers and for Indian conditions):
