From here you should have more than four hellions to control the map and deny creep spread and if possible get into the drone line to do some economic damage, but it is not necessary to sacrifice your hellions for drone kills. The starport should start researching cloak and producing banshees as soon as possible to harass and kill queens in tandem with the hellions. The game can progress in many ways, mech or marine, medivac and tank compositions are the natural progressions from this build.
