Source setup, does it look right? Pic in the comments

Been vaping concentrates for awhile and I've always used a gentlemans vape brand pen because put simply it worked. I like the pen concept because I can bring it anywhere and don't really care for the huge batts because it's not very stealth. That said, I've put together what I think is a decent little package here:

Would like any feedback, or if there's something I'm missing.. Don't really wanna buy a kit plus the big rig and a whole bunch of carts I don't need.
