Signals Design Overhaul

These are the four protagonist characters for my scifi dungeon crawler concept, Signals.
In order, they are the Architect, the Pilot, the Sentinel and the Renegade.
The newest version was developed over the last year under the tutelage of my mentor, Sean Yang.
I feel that both versions of the designs have their own merits and both convey completely different tones for the same base idea. The rendered version pushed me to work on learning how to paint and render while the older version has clear, distinguished characters.
In the future, I think I'll try these guys again with a sort of middle ground between both, but also something completely new.
