This model looks great. The paintjob, the details, the overall realistic look of it.
I'm having a hard time believing it's your second model.. don't get me wrong.. I believe you, it's just that I have to force myself to.
So when you say second model.. is this your second "car" model? Are you an armor, or airplane guy that decided to build some cars? Did you have a model mentor, or did you learn techniques from the web, or magazines?
Don't take this post the wrong way, i'm not trying to sound skeptical, it's just that most people's 2nd model doesn't end up this detailed, so i'm just a little curious about your background and where you found your technical know-how.
