SciFi and Fantasy Art: Flying Romans and the Gaul from Hell (final)

This is a drawing for the RPG my friend is developing, so it might actually appear in print one day. He wanted a drawing with realistic costumes and armor, and this is my attempt. So I looked up info on armor, weapons, etc., and believe I have been fairly accurate. The armor is scale, with a tunic underneath, a skirt, and a belt with a bit of dangling armor to protect the privates. Short swords without hand-guards are carried by a sash in a scabbard at the right hip. Helmets have cheek-guards and a slight, um, ridge or visor above the brows, as well as a hole and a couple clasps for holding the crest. Cloaks and helmet crests are removed before battle, except for the Centurion's (distinguished by the sideways helmet crest). Legionaires also have daggers, hob-nail boot sandals, and a shin guard for the left leg. Based on what I read in multiple history books and web pages, they throw javelins and close, legionaires spaced a bit under 2 meters apart.

I have also attempted to be accurate with the Gaul. Armor was sort of optional for the Gauls, though the nobles prefered it (small wonder). Even shoes, shirts, and pants were optional. If worn, clothing tended to have designs we would call gaudy, with stripes or checkers being common. Gauls put material (I forget what what it was called) in their hair to make it spikey or scarey-looking. Sort of like a primitive, dirty, whitish mousse, I gather.

One things I wasn't sure of was the proper shield shape: Were the shields in the time of Augustus still oval, like they were in the Punic Wars, or had they switched to the later, rectangular shape by then? I couldn't find anything that said. I kind of compromized, making rounded rectangles, which are probably not accurate.

This Gaul's monstrous physique is due to several powers from the game that he possesses: super strength, claws, and fangs. Due to his natural weaponry, he has chosen to fight without without the traditional huge sword and throwing axes.

All that aside, I still wish I had done a few things different. The legionaire on the left looks awfully stiff. The Gaul's waist might be too thick. I still seem utterly incapable of a smooth transition between foreground and background. And I wish I would have drawn a bent pilum (javelin) or two on the ground around the Gaul. However, I do like the Gaul's muscles and pants, and the kind of 'Hmm, that's not supposed to happen,' look the centurian wound up with (it shows up a little better in the actual picture).
