Nice, painterly style
2D skillzz shinin' through! I like the way the shield is rendered, however I think it would look a lot better if the design were a bit more interesting. I think that might be solved if you added another color in there somewhere in the form of another metal, or some jewels, bolts, or something.
The orc is really cool! I love his face especially, and the way you painted his skin. Except it looks like his neck muscles/tendons whatever should be taut, but instead they look wobbly. Unless that's like excess droopy skin or something? but it's not really reading like that either.
His armor could use some work imo. For example his shoulder pad thingies look like they were cut out of cardboard and there's not too much sense of construction. I'd imagine there might be stitch seams, some wrinkles/folds where the spikes are connected, scratches, etc.
The lighting on the belt looks a little funny too, there's lighting on the top, but it seems like there should be a little ao there instead, where the studded belt rim meets the rest of the belt - right now it kinda looks like that area is glowing.
I really love your painting style though, so keep going, can't wait to see more :]
