The biggest issue is your lighting... dark scenes are really difficult to do. But in general you still need to light your scene well enough that people can see your charecter....
It seems like you felt you needed to have you light sorce comeing from the torch alone ... you really dont... remember light bounces exist.. and trying to replicate them in 3d space can help you light your scene more clearly...

In general you should prioritize a good looking light scheme over an accurate one....

Best of luck!
