in the scratch design * the curve into the bell is too shallow * the tube leading up to the bell is too thick * the valves are on the wrong side (they should be in-between the tube coming from the mouth piece and the one leading to the bell) * the valves aren't actually connected to the trumpet in any way * if you were to play it it would play like a bugle and the valves wouldn't do anything * there's no lip for your right pinkie to rest on * there's no lip for the left thumb to hold on to * the tube leading up to the bell isn't long enough * the tube coming from the mouth piece is too short * the entire trumpet is too tall/thick * the mouth is the same color as the trumpet (while brass mouth pieces do exist most mouth pieces are silver. * the tube connected to the middle valve is missing * the tube coming from the mouth pieces isn't connect to the 3rd valve, also there's no handle to change the tuning slide
