Seraphe your build looks pretty good, but it's glowing more towards the top than the bottom. Pulse it a little more, prod the coils a little to get rid of the hotspots.
Remember if it glows evenly from the inside out, you have to do it at least 5 times consecutively to make sure it is really swee swee stable.
Looks like you only have 3 wraps though. On gennies you should try to aim for 1 ohm and above. You are chasing for flavour after all.
Your wick seems a little thick too. Remember to not completely fill the wick hole with mesh as you want to let juice to breathe and travel up the mesh more easily. The more mesh there is, the slower juice wicks up.
I'm assuming you're using #200 inner and #400 outer?
Also to help against hot spots always triple oxidise your wick first to make sure no spots are uncovered.
Carbons help to prevent hot spots. Before you put your mesh on the nextgen, drip some juice on your wick and light it on fire. Hold your wick till the fire goes out. Repeat thrice and put it on your nextgen and coil it. Hotspots should disappear quickly now.
