This is the RX-79(G) EZ8 from MSG: The 08th Ms Team and is piloted by Shiro Amada, who happens to be one of my favorite characters in the series. It didn't quite come out like I wanted because I had to fight with my scanner, but it'll do
I like the Ez8 for being so darn realistic; They basically threw it together out of spare parts, and it doesn't have a classic V fin for that. 8th MS Team in general is a very nice concept for me. I like this drawing, too, nice, defined lineart and solid work on the shading. Props, bro!
