No I found his DA page and sent him a note. He's very friendly and very reasonable. Did I mention fast? He did this beauty this morning after I talked to him. Maybe 3 hours tops! I might get someone to ink/color this so if you can recommend someone, send me a note.
I think it just depends on the artists style. She's a big muscular Russian girl, definitely bigger than say Wonder Woman or Fairchild. Best I liken it to is pictures of She-Hulk: some have her slim and athletic, others have her bodybuilder class. Just different artist takes.
Thank goodness you weren't comparing Olga to Lin as it's no contest. Lin wins in the bideps category hands down!
