Have your S2K ant. painted either blue or black (I would go black)
Either add some white stripe decal to the side of your car, or have the skirts painted blue to match. (stripes of a similar style to what you have on the Hood
Put something on the top that's white.. Don't paint the whole thing, but add some stripe, or design, or something, so everything blends, and the top doesn't seem to dark (which makes the other white parts look funny... They stand out too much, I think).
Same with the spoiler. Paint it blue, and find some sort of white designs to put on it. (again, something like a continuation of the stripes would be just fine.)
And finally, you could look in to having the "CELICA" that's on the hatch overlayed in white.
I know, it would take time and money to do these things, I'm just giving suggestions, not telling you you have to do it or anything
I think it's unique, and from the front end, I think it's pretty cool. The rest is OK, and could be cool with a few modifications, in my view.
Of course, if that's the way you like it, keep it that way! If you own her, it's all about you
