New pistols (first GFX attempt by me) any sugestions?

[Switch]

Okay well I was doodling in Photoshop and came out with the side view of a gun so I decided "What the ****, I'll make a complete gun GFX!". Although it looks similar to a RP and/or BP RP and BP were NOT a template. It was JUST a doodle at first. Also if I see you using this ANYWHERE (unless making your own color version to post RIGHT ON THIS THREAD AND NO WHERE ELSE) without my permission or I will report you so quickly you couldn't change my mind. I'll need suggestions like color, where to put detail, and so forth. CONSTRUCTIVE CRITISISM ONLY for the template (unless acompliment ), nothing more.
Note: Farthest left is left view, right of that is right view. Farthest right is front view, left of that is back view. Also I didn't decide on the size first so they're not pixel sized right now.
