Creating an Outline (Rifles)
Step 1;

Ok, first your going to want to choose what you want your barrel to look like. So just make it about 8-10 pixels long at most, and make sure it looks like the barrel of a gun.
Step 2;

Now you'll want to do an outline of the "nose" of the gun (I guess?). The part that connects to the barrel.
Step 3;

Ok, now choose what you want the "Body" of the gun to look like. (The rest of the weapon). I gave it sort of a redrifle feel, or so. (The way it rounds off in the back a little)
Step 4;

Now design the insides. Remember you can add anything you want in here. Sometimes it doesn't even have to make sence, as long as you shade it right.
Step 5;

Now, you just have to color it.
*Note;
Remember, just because the outline doesn't look to good to you, always color it first before tossing it away. You'd be surprised what things look like with a bit of color.
(If someone could attach this to my first post, and delete this part, it would be nice.
