Looks solid. I don't see anything glaring that absolutely needs adjustment, though I have a couple recommendations to consider and/or test.
First and foremost, I think your deck needs more Ronin and Melange. Ronin is amazing, and having more than one mitigates bad draws, or if it's botched and the runner trashes it. Melange is great if played early, and even one turn of it pays for a lot of Jinteki's ice.
How's that Priority Req working out for you? I'm guessing it's purely for agenda density and you shuffle it back in. I had done the same for a while, though having one stolen hurt far too much to warrant it staying.
I'm personally not a fan of Celebrity Gift in Jinteki, nor SE (good players predict it nowadays), though both are in a lot of good decks, so I think it's more a matter of preference.
I'd toss in a more punishing ice for late-game, such as a lone Archer or other sentry. Additionally, I'd make use of your Ice Walls and Braintrust and throw in a couple ToL. Aside from that, that's pretty much it. Snowflake and Himitsu Bako are also worth considering, as they are much cheaper and allow you more wiggle room elsewhere.
