Here are a few WIP pics from my current project: A 2009 Dodge Viper SRT-10 ACR.
I began this project two years ago as my second attempt at modelling a car (for my first car project I created a fairly crappy model of a Lamborghini.) After a poor first attempt at modelling this car, I threw out the mesh and started from scratch. Eventually I came up with another much improved version (though still not as good as the current) about a year ago. I though that I was done with the project but in the past month I have taken it up again. I thought that I would share this with you guys and hopefully get some critiques and advice as I continue working on it.
Once I achieve a good enough result I will probably put this model aside as a side project, and update it off and on with more details. There are still many things that I could add to this model such as a detailed interior or a rig.
