Storm and Sierra
Unfortunately, they don't have any official character page for Storm so I just went off of others' preconceptions of his appearance. I used the combined references of TheXLuckyXOne and blackhorsebeth for Storm's design. I hope you like it!
I'd also like to let everyone know that I am currently taking commissions until October 4, 2015. That's exactly a week from when this was submitted. Please, Privately Message me if you have a request or would like more details. (The commissions are free of charge)
