Not bad! I’m guessing he’s some kind of water-related hero? :)

I think there’s some problems with perspective. With the angle of the sword hilt, I feel like it looks like the sword should be stabbing into his shoulder rather than resting on it. I’m also a bit confused about the shoulder pads - maybe I don’t understand how they should look but wouldn’t the sigil with the trident point upwards? That’s what I’d expect from a shoulder pad. Would you see it like that from this perspective?

There’s also missing a light source. With his pose, it might make sense to have the light coming from the left (or where he’s looking) to illuminate his face and left side more than the right. The lighting is flat as is.

Keep at it, I’m sure you can figure those things out if you practice. :)
