Absolutely beautiful!! I love how it's turning out! I didn't see how it was before, but I saw that you wrote that it's work in progress. I love the flow of colors and color choices you made! They all work wonderfully together drawing your eye around the image to where it works together instead of as a giant mess. I like how the flowers work together and then the leaves lead your eyes to the lips, nose, then the eye on the left and work your way back down the blue. It frames the face wonderfully! If I were you I wouldn't darken any more of it unless you were to add a little bit of pink or red to the lips. Trust your artistic judgement! It's turning out absolutely amazing.
Your use of desaturated colours, as always creates a deeper sense of emotion in your portraits. This artwork is no different. Its wonderfully emotive and captures the eye perfectly. What it does better than anything else, which a lot of people who try and follow your style miss, is it holds your eye. It is difficult to pry myself away from your artwork because there is so much to see and so much to be amazed by. Your use of line is nothing short of absolutely spot on! adding the lines create a wonderful added depth to your image. This piece is both peaceful and relaxing to look at, but still very dynamic and stirs something in me to want to go out and do something amazing. Your style is unlike anything I have ever seen. Sure there are some that mimic it, but you have the bar way to high and the technique down to a "T".
Just as an added note, you, in my opinion, are one of the best artists out there. One of my top five favourite in the world who still live today (each having a different style so I can't pin them down further than 5). You are one of the artists that inspired me to pick up my paintbrush again!
