About this 3D model

first post so be gentle this is WIP so i didnt know if there was an appropriate place to put it. it is going to be a model of a glider of sorts. i was planing on pcb milling it out of brass but that didnt go as planned so i think i might laser cut it later on. i know there isnt a final product to comment on but i would appreciate any feedback on what might go wrong, or help from people gurus of laser cutting.
