you need to take into account that its going on a sphere and rotate the air vents on the mask so they show up as perpendicular when they're fully mapped on the head
also dude when people point something out to you dont just make up an excuse such as "i like it this way"
people like tpk are the people who will help you get better and evole your art in ways benificial to you.
heres what i have to say about this head
mask isnt mapped right if you like it dont change it but it is. when you get to that point ots best to flare the design out so it wraps to the correct size.
the top of the head wraps into a dot so avoid drawing lines into the top of the head when getting it to wrap at the top feel free to look at mine to see what im saying
