I'm "new" to blender (I haven't used it in 3 years) and I started modeling 2 days ago. This is something I made, Incase you can't see it... Its a flamethrower.

Its inspired by this

I would love to hear some criticism and how I can improve.
Its a nice model, but the logic is a little flawed.
I'm guessing the gas comes from the top tube, but what does the bottom one do then?
usually on flamethrowers you just have an igniter below the gas outlet.
In the picture you were inspired from, its a rag tied on the end of a pipe. Maybe you should think about it because at the moment it looks like it just has two outlets for gas.
