Okay first VERY nice art I love the pose and the ships very good job. Now the bad the hands they are WAY too close togther for a good grip. For most sword styles the dominant hand is near the blade and the weaker hand is near the pommel cap or end of the hilt the part you grip. The reason is to create a lever motion with the dominant hand pushing while the weaker pulls creating more power. In this picture it looks like her left is dominant while right is weaker but the fingers are so close that their grips will get in the way of each other. Outside of that nice posture if she is left handed she would bring it to her left shoulder for a power swing with right foot forward and left back to be able to put her hips into it. A good idea for potential or even action pics is to plan out what they are doing in real life and feel how it sits with the body even if the moves are beyond you the basic motions and postions are not and that understanding will help.
Oh, wow!! This would be right at home on a classic cover! I love how much you've managed to communicate with this image - it tells a story by itself of the Exile as the General throwing herself into battle. Your detail is exquisite and everything about this has been crafted with so much care and attention. Your colour range is vibrant and dramatic, and so much about her is so well communicated - her hair, the look in her eyes and on her face, the way her robes sway as she throws herself into a combat dance, and your use of perspective giving us such a fantastic sense of scale with the destruction in the background and the enemy right above (or reinforcements?). I love your careful attention in the way her hand grips the hilt of the saber and the strong glow of the blade. Against everything, here's the Exile at the centre of battle, charging in!! It's awesome, and communicates your vision and the emotion of the scene very well. This is very cool Thanks for sharing!!!
A very beautiful and classically rendered illustration of a personal favourite character of mine indeed! This piece would be right at home on the cover of a Star Wars Bantam Spectra novel back in the day. Magnificent work
