Actually we both happened to use the same photo reference. Hers came first obviously but I didn't know until someone else pointed it out to me. I would've linked the reference but, alas, I can't find it.
Well, unintentionally... A few people have pointed this out to me and it seems Burdge and I used the same photo reference for our drawings. Hers was of course first but I didn't know about it. Oh well, more Lily and James love to go around, right?
