First time trying to make lora concept, trying to reproduce action of 'metalheads' and not only. For simple use with checkpoints, use strength around 1.0. With other LoRAs, you might need to increase up to 1.3. Not always necessary, but better to put 'guitar' and 'playing an instrument' in negative. Holding a microphone, stage, speakers appears in my tests much less often, but you could put in negative too. The LoRA does not put a strong effect on the face of the character or person, but will have an effect on facial expression. For 'hair motion blur' checkout your negative, or embeddings if you use them.
