Here is my take on my favourite gundam - Deep Striker (or more accurately the MSA-0011-3 [Bst] PLAN 303E Deep Striker). The intricate shapes and curves, the numerous parts that are made up of smaller parts and the sheer attention to detail from Hajime Katoki will make any art associated with Deep Striker bound to be a challenge. And it was, drawing reference from my 1/144 model, I was able to accurately reproduce the lines. So I think this line artwork is probably the most accurate representation out there.
