This is so awesome!! I plan on drawing him soon as apart of a ninja series. Your piece is way better than I am ever going to do though! I love how you did his mask and upper body. His pecs and abs are drawn very accurately and are well done. The colors and his posing are fantastic as well. Overall it's a great job!
Thanks. I used a reference when drawing this. We just need a lot of practice to improve our art XD I still need to practice drawing a background. The background here is too simple. I might draw another Hayabusa art if I have time. So many things to draw, so little time
