I love white F355's
Get those front rims fully inside the fenders and it will look a lot better. The wheel design looks okay to me; perhaps if they were painted bright silver like real Ferrari wheels they'd look more appropriate.
I see you got bitten by Fujimi's incorrect drip rail/window trim; they engraved the trim over the door glass though it's not supposed to be there. Look at any pics of real F355's and you'll see what I mean. To get rid of the mismatch over the side glass vs. quarter glass, you could paint the part over the quarter glass black to match up. This kit is not one of Fujimi's better efforts...by a long shot...but they still look cool when built, as this one shows.
