Hi, working on a set, heres some pics, thoughts?

Be gentle, I'm kinda useless.

Also this is the first time I'm doing anything more than a head tex...

I've put in three pics ingame, but uh, since I don't have 512's they're kinda pixelated.

So I put in a GIMP sphere map but that also lost a lil bit of quality.

The head needs to be more noticable.
The set is simple but really good for
a starter.
6/10

How would you suggest I make it more noticeable?
Also I'm kinda making this in between studying for my Medic exams.

By more noticeable, He means make the colors "Stick out" Not just one bland color.

Like that?
