BlackJack@ I agree with all that Reconnoiter said. Perhaps you could take a look at the way weapon changing cycle made in DooM 4.
As you cans see, in your case using model (animated) looks pretty nice, but it's not useful at all, in fact it actually disturbs you, by blocking most part of the screen! So while you enjoying all the fancy look of animated cycling things, enemies can get by you and punch all the health points out of you Look how it's made in DooM4, TRANSLUCENT! and the main part of the screen is not blocked (even if it's blurred). Anyway, it's your game, keep it up! It has some nice looking style (borderland's style), but I really hope it won't be one of those projects that nowadays made, where visuals are pretty nice, but the gameplay part is not that good.

FLD@ it looks good, but it's not made with physX, am I right? I'm saying that, cause to my taste the way it climbed up the hill was a bit not realistic.
