Well, that's great on speed... really, not bad 'tall.
Realism-wise... well, what kind of hellish environmental is this poor chair exposed to? What physical process resulted in the patterns of damage and wear we're seeing here?
Yeah, yeah, I know, you probably only had, what, maybe 30 minutes to do the skin... don't bite me, just askin'
But what sticks out, for me, right away, is the very weird places paint is missing- makes it look artificial right away, imo.
Also... that's for a HL2 mod, right? Feels a bit low-spec for HL2, both in terms of tricount and the skin. But, time-wise... eek. Dunno about 1 hour, that's asking a lot. I'd say that 1.5-2 is a more realistic target, and that's assuming that the normalmap / specmap isn't fancy.
