Nah... I don't usually consider commission as commercial since you probably aren't taking commissions as part of your career, lol. Plus, using references and studying your subject is key to actually achieving accurate anatomy and overall improving your skills. Even some of the best artists on dA admit that they sometimes use references or they do a lot of 'research' before they draw. So feel free to use them ~
I should certainly hope they're researching stuff! I do the same and awesome x3 thank you so much! This is a great shot btw. You have a knack for getting some awesome poses!
I'm glad that you think so! I try to post a variety of poses for drawing refs but it seems most people just want stock for manips ~ It always makes me happy when people use them as references too!
