Its looking good, but the yellow and red too often ruins a model for me because I instantly think of that stupid Ronald McDonalds dumb ass suit.
If your parents are complaining then just tell them its something you enjoy doing, try to spend less money on them, I try not to spend much. If the main reson is because you spend too much money on them then just buy a normal kit, buy some spraypaint and primer for it and just take your time, build them when your parents aren't home so that you don't rush.
