HI there! That's a great picture, just couldn't past by it. So here is some critique (constructive I hope) from a noob artist like myself. Ok, so overall it's a great piece and bring the mood of golden autumn with it. I like the composition with light top down to darker bottom. Top is clearer bringing attention to character with detailed bottom creating the atmosphere. I love your coloring style and your shading technique. Specially well done with metal parts here. I also love the idea to combine brush styles for hair. Althou the top curl was a bit overdone in my oppinion. The main issue is some disproportion of her hands. I like pretty much everything about her right (front) hand, though the left one is comparably too long, also a bit strangly twisted. I guess that's a challenging task to keep proportions right for the dynamic poses you choose for your art setups. But solving it right would drive your art from great to awesome! I suggest you to use references like action figures for the purpose. Hope this was helpful. I wish you good luck and well delivered resulsts in you art!
