Well I had started another space soldier character in zBrush about a week and a half ago. It's not done yet, but I was working at school on it Friday and zBrush or the computer wouldn't let me get very far without crashing every few minutes for whatever reason. So to blow off my frustration I decided to sketch him out instead. I needed to fine tune the final look of his boots, gauntlets, and gloves anyways. Funny how none of that came to fruition when I got as far as I did with this. I'd like to work more on it, and I might in the future. It seems decent enough to stick in the back of my portfolio or website somewhere when I get those ready. Not really sure about the pose, it was just how the original sketch ended up, and I wasn't really thinking about it when I started. Also his name is Davy, one of my friends decided that was what he should be called, and from that point on it was so.
I even managed to work on this in a way that kind of looks like a tutorial, so I figured it couldn't hurt to upload that. So here's the process behind Davy:
1 - Rough Sketch
2 - Block-In Lights and Shadows
Did this in a new layer under the sketch.
3 - Refining
The longest part. Just defining each part better, adding finer details
4 - Atmosphere
Rendered out some easy clouds with Photoshop and stuck 'em over Davy. Erased the area over his arm to make atmospheric perspective more apparent. Easy to remember as well, darker = closer and further away = lighter (actually by lighter I mean closer to the background color ex. the sky)
5 - Fancy Lights
This is just me trying to get more bang out of this, I already had highlights but I felt like he needed some more. Just went around with the soft brush and painted in the lights. Then went back with the brush at around 10% opacity and built up the glowing aura around each light. It was the same process for the highlights I intensified on his visor and shoulder.
Here's a little GIF of the whole process above, enjoy.
Hope this helps somebody out there.
