I've got this Idea for a while now, it started out as a sketch for Rainbow Dash until I eventually started working on the full art!
This art took me: from 4-7 hours? I don't know, since I am doing University and working, my days have been really rushed, usually I drew 5-10 minutes a day, (safe from weekends, where I invested more time) and it took me 3 weeks to finish, soo I think it's around that time!
