First of all, let me point out this was a paint-over. The reference I used was adonihs's "Just a Grunt" piece. Before anyone claims I ripped, I already got permission to do it. You can view the much nicer original here:[link]
Now, while I did use adonihs work early on to get the line art, basic color layout for the marine, and ideas for lighting, I didn't use it as a crutch. After getting the basic components of the character down, it was pretty much all me.
Anyways, I didn't even mean for this to turn into a real, finished piece...I originally was just going to do a simple paint-over to get coloring practice but it came along so good I decided to submit it. You can tell parts I rushed and parts I spent too much time on. If some of the lines seem sketchy, its because it was done by mouse which is damned hard to draw straight, even lines with.
All drawn by mouse in PS, around 10 hours.
Hope you enjoy...and make sure you check out the original!
