Slicer- Unfinished

The second addition to my Ben 10 alien Re-design collection. The original concept drawn by Here's the original:[link]

I don't entirely like the way his legs turned out... but oh well, anyhoo, my finished version, like my other ones, will be the sketch, colored on photoshop to make it more defined, and in an "omnitrix-ish" fashion, mainly meaning it will have its emblem on it.
Look at Xelku9's original for the initial powers of this alien, but here's my bio:
The creature known as a "Slicer" comes from a planet that is notorious for it's giant insects. The name is derogatory, as it has some of the strongest and sharpest blade appendages known to human(oid)s. It is essentially an enormous crossbreed between a tarantula and a praying mantis. It has been known to cut through objects much harder than metal and eat objects just as strong. It's powerful jaw can tear through metal like moth eats cloth. Also, as a hunter, it can use its large blades and insect speed to catch its prey. When it catches food, it uses its middle arms to pic up the raw meat.

Feedback please?

Also, my Ben 10 picture will have a superhero bio, and will be colored.

Yes, I know I spelled it wrong on the top. And I am, sorry.
