You can use https://wiki.multitheftauto.com/wiki/CreateEffect to create fire, and update the position of the effect every frame to match the player's head position, using https://wiki.multitheftauto.com/wiki/GetPedBonePosition (BONE_HEAD).

The fire in your picture looks like a custom effect - probably part of the model itself or some kind of tricky shader... however you should still get fairly close with what I suggested.
