Not really a fan of this kind of two-tone myself, but everyone has different tastes here.
Personally i'd change the front bumper back to white and then paint the vents on the hood black, or put the stock hood back on.
What else where you planning on doing with the car?

08 Altima Hybrid
98 Prelude - SOLD
If you get the Carbon Fiber Fenders you will complete the look! but I would personally just paint the front bumper & the kit (white) i think everything will flow better...then just get the 11-12 LED Headlights that makes everything bette!! lol
LOL, yeah I noticed that too! International car? hahah!
For a secI thought the interior was two-tone as well as in the Japanese car which has that for their artworks car.

Is it just me or do the rims seem to get lost in the whole setup? I'd recommend making them show a little more - perhaps painting the calipers red/white even would make those awesome rims come out a little Could throw on a lexus decal - there's a whole post dedicated to this on these IS forums if you're interested in that.
On the rear, I think making the Lexus logo shine again would provide some nice contrast, instead of keeping it blacked out, even if you keep the IS250 and the word "Lexus" blacked out, I think the logo would look good to contrast the rear a bit.
