Advanced LEGO set for my 5 yr 2 months old child

2018-04-19 11:41:24

My Son is considerably talented in LEGO building. Till now, he has completed over 30 LEGO sets all by himself which includes this year completion sets - 42054, 42064, 42072, 42073, 31010, 3367 And 70625. His very first LEGO set was built when he was three years old - 40220.

Now looking for more challenging sets for him. Any suggestions?
