Here are my opinions:

1. Style, the conversion idea is very nice. So far, looks like it's progressing well. You just need more time to finish it up.
2. What's missing: All that paul said (admin). Drop, better wheels, nicer exhaust.
3. The bumpers are a bit aggressive. IMO, it'd look better with stock rear + Lip. For the front, it'd be fauking hot if it's a mugen front.

As far as the other people that's bashing your car, don't give a shit about it. For all I know, many that talk trash are generally own stock or slightly modded car. Heck, I even saw a bunch driving run down car. It's the internet, don't sweat it, they can say all the want behind the computer.

Also, what Julio said may be a little to harsh, but he's speaking from experience. You post your thread, and criticism are to be expected.

Do what makes you feel better, just don't make it too extreme or aggressive. Goodluck.
