This isn't bad... the textures are all excellent, very well done there, but the model just has too much going on, and the front hand clips the grenade launcher because of it... it's way too busy looking... and I can't in good conscience give anything higher than a 5 for the animations since as far as I can see, they're just Valve's... prove me wrong and I'll change it...
The textures are very well done, but some spots don't seem to match up, and one spot drives me nuts... the rail on top for the scope is WAY more detailed than the body of the M4 that it's attatched to... looks strange... the grenade Launcher also looks more detailed than the fore-grip of the m4...
Lastly, the whole model looks somewhat stretched, and I'm not sure why that is, but it's not a big deal, might be the origins... the worlds are excellent and look huge and scary, which I like, but in other player's hands, the forward hand clips the grenade launcher, but again, not a big deal...
A good start, but not my cup of tea... keep it up :)
