Be prepared for a lot of admiration in a poor words, because my english is bad.
First of all, I absolutely love your style and it's amazing to see them drawn by you. I think I've mentioned it in one of my previous comments, I adore the way you draw hair and folds. Their expressions are great as well; Florimel seem to be happy and confident, while Erandur content and calm (that fits their personalities, I think). When it comes to basics - they are absolutely recognizable on the first sight and I love the simple shading you're using.
I can also add that I'm super chuffed about how it turned out, but it's pretty obvious, right?
Oh, and I'm amazed by your speed, I've never before got my commission that quick.
Thank you once again! I hope you had fun with this work.
