I made the exhaust flames very large and bright to emulate the ships in Battlefleet Gothic. However, if people would like me to edit the exhausts a bit or keep them as they are, then I have created an anonymous poll you guys can vote on to resolve this: https://strawpoll.com/polls/XmZRx6N76nd I'll close the vote in exactly 3 weeks time from this comment and adjust the exhausts according to the most popular option.
