Ben 10 aliens- Upgrade

So i'm a BIG Ben 10 fan. Understatement of the century (He does share my name you know). I love the original series but alien force (while entertaining) kind of disappointed me. Thankfully ultimate alien causes a tingling of hope within me.
Since I love Ben 10 and I have re-awakened my love of sketching, I have decided to try and sketch as many of the aliens as possible. They may be pencil and pen or they may be digital. Heck I might even sculpt one or two.

So let us begin our alien adventure in no particular order. Ladies and gentlemen I present Upgrade! *insert applause here*

Yes that is an upgraded lawn mower...
