My opinion is that is way too much crystal malt for an IPA. I would cut it down to 5% total or so and it may not hurt to simplify and only use one type of crystal malt. The oats I would either remove entirely or up the amount to twice as much.
If it was me I would go with something like:
10.5 lb two row - 82%
1.5 lb flaked oats - 12%
0.4 lb Crystal 40 - 3%
0.4 lb Caramunich I - 3%
That will change the color significantly. If you are shooting for Ruby colored you will need to get closer to 15 SRM in my experience. I would use a small amount of huskless roasted malt to get there. Just my two cents...
