I have little idea who these two actually are, but I'll get ideas as I go along. Praeton's slowly forming as a character within my head, but the Matoran is still unnamed. It's probably a 'she,' but that's all I've got.

Praeton is a Toa Viso, (a team from my epic "Thunder," though only two members of the team are present) element unknown, mask power unknown, weapon, Kanoka disk. He's a bad guy. Also not a Hordika, unlike Vano and Amana (the two mentioned).

Here's the two, side by side.
A bit fuzzy, but...
The Matoran on the back foot.
Readying disk
Silent and deadly
Kanoka expert
Going for the throat
Fighting back
Upper hand
...Or not
Countered
The bigger they come...
...The harder they fall

Here's all my Toa (and the unnamed Matoran)

Here's that Matoran's upgraded sniper
And again, with less 3D detail, but a sharper pic.

So... Thoughts?

I love the "silent but deadly" part.

The red guy: I like the Zamor sphere launcher as a torso piece. I tried that once but it didn't work at all. You appear to have pulled it off. The only thing I can see wrong with him is his lower legs. They're a little plain. :/

Matoran guy: I like the black Kakama. Very nice looking. I also absolutely love the sniper rifle. The use of that triple stick thingy is very good. But I still think their (her?) legs are too long though. Maybe you should custom make them like Toa Takal's lower arms.

Yeah... I've wanted to use a Zamor Launcher as an effective chestplate for a while now, and now that I've got a Zamor launcher and a Kanoka launcher in one? I'd say that worked quite nicely.

I've still to find something to use to pad the legs... Any ideas?

I can't make any more custom legs - I've run out of ball bearings. What I really need - and it pains me to say it - is HF limbs. Yeah, I like the sniper too. I guess she was built around it.

Maybe Nuara back from Karzahni? I don't know, it's just a suggestion.

As I said in TTH, they're good, and my only complaint is the matoran's legs. Oh, and, would it be a good idea to mock my first attempt on my own first MoC page?
