1) If that's cotton, it looks like it may be too much, and the wick layout isn't ideal for any kind of proper wicking for clouds. You'll want some fluffy babes going on like the pic I link below, except better cause it's my lazy *** build LOL.
2) Don't order those coils again, I think I may have wrapped some better while drunk.
3) You have good batteries, the efest 2500's are 20amp drain and good down to 0.23ohm with a safety factor.
4) If you're getting 28 gauge I would spend some time reading up on parallel coils, as long as they don't take forever to heat up (Too many wraps), parallels can yield some awesome vapour - more surface area heated on juice = more vapour. One of my favourites was clouding up the local B&M vape shop with a 28 gauge coil at 0.40 parallel build and it freaked some guys out cause the vape was also cool.

Not a pretty build, however she clouds fairly well. The wick is the big key, and probably the most overlooked part. Fluffy rayon or cotton, tucked gently underneath and leaving air flow around the coils. There's a ton of youtube videos to help you out, and it DOES take some experimenting.
