how’s this set up for a newb?

Hello vapers! I’m new to the vaping community, I smoked a few of my friends mechanical mod and got hooked, hoping to quit smoking analog cigarettes currently, this seems to be doing the trick!
Just a few questions, as in what is the weak point of my build or do you guys have any suggestions for my build?
Got a good deal on this from a buddy
Authentic 4nine mod
Igo-w rda
Unknown drip tip
Nano dragon dual coil, I believe my friend wired it for somewhere around 0.8-1 ohm
