I've been working on this for a few months and is the most complicated drawing I've done so far. I had thought about doing it before but knew it would be a ton of work, in reality it was about 10 tons, seemed never ending.
I decided to just do the front half to better show off the engine but I could re-use much of it if I ever wanted to do the whole car. As before it's just the pen tool, gradients, blurs and blend modes, so anyone could do it.
Hope you like.
