Personally the weapons look a bit too small to me. I feel like there’s too much negative space between them, and they need to be bigger or there needs to be more of them (or both). Possibly even a sword/weapon backdrop sort of like the GoT throne
Great work so far though!
The original goal was a portrait idea. So making the elements other than the central figure bigger or more prominent kinda goes against that idea. Making the weapons bolder would detract from the focal point figure.
Maybe keep the weapons the same size and add some amorphous background design between them to make the Owlbear pop more?
