I see you are using advanced_shield.shader that is pretty much the same as game's default.
Maybe you should change
Shader = "../advanced_shield/advanced_shield.shader"
to
Shader = "../../../Data/Ships/Terran/shield_generator/shield.shader"
UPD. Also, small reactor uses identical textures/sounds as normal reactor from the game, so it's better to use those instead (mod will take less space and less files to load).
Same for steering_thruster->roofs (armor) and windows (small_thruster);
armors (blueprints, floor, roofs, tri<...>), durasteel and doonium armors look same (?), also durasteel armors don't have UsePartWhenFlipped attribute in txts;
shield generators->sounds, shield_energy(_wave).png, roof_windows and shaders (along with base.shader);
red, green and blue blasterlasers (and x-wing laser) use lots of identical textures (also green blasterlaser's files are named blue_pointlaser.txt for some reason), so this can be optimised as well.
same as above for cockpit and cockpitTIE; all 3 astromech armors and all 3 turbolasers.
