After lots of trial and error, here is a model I made featuring the tall muscular main character "Goliath" from the series "Gargoyles". Please forgive me with the quality of the eyes, as that was the most difficult part of trying to train thie Lora itself to make this work. Helpful words based on what went into this are:

goliath, bara, tall muscular figure, flexing arms, muscular pecs,, muscular arms, loincloth, black hair, tail, highly detailed face, highly detailed eyes, looking at viewer, serious face, arms at side, high quality, large open wings
