So this is an old gift from a friend that I wanted to upload here. It's from a few years ago, but I still look at it sometimes and I like it a lot. It was drawn by  vitrex for my birthday almost two years ago now. At the time I was in the last few months of my Master's degree for mechanical engineering, so it was also a very nice congratulatory gift with respect to that.

I also think that it's a good reference pic, pretty complex angle that covers a lot =p

Thanks again!
