This is how I think Sektor should look like, the face was sort of inspired from MKA Concept, hopefully I'll do a Sektor ninja when I get a few ideas. Hope you like. ENJOY :D P.S. More Art coming soon.
Looks pretty cool. Looks like you used Jax007's style and the MKA concept for inspiration. Your lines could be smoother, and work on the upper legs some, but other than that it looks awesome.
