Mercedes SLS AMG

Update 16-03-2016:

Heyaa

As you can see, I finished this one It took a hell lot of time and yea...there are a few issues but I don't bother to much about them, it was a fun piece to do
Just to give an idea where I got the reference from; About 2 years ago I visited a local car dealer who had this SLS in his showroom, so I asked if I was allowed to make a photo of it so I can draw it eventually^^
Now, 2 years later I finally had the time to do it, well..actually I started it 1,5 year ago already but, school took a lot of time and at the end of the day I wasn't in the mood to draw, and besides; I only draw with daylight
