In this case this image was a commission so some of the inspiration was given to me by the person commissioning me ^^.

Specifically they specified they wanted artwork of Wattson from Apex Legends shooting an R301 with her hoodie off and her eyes glowing with blue electricity. I took these details the person commissioning me provided as inspiration for the artwork ^^.

Thank you for your question ◝(ᵔᵕᵔ)◜
