I really like how he considers real Lego expectations (durability, part count, etc) when creating his Mocs (especially his alternate creatures) as if he was a designer himself. He doesn't just go for "biggest, baddest, coolest" that most Moccists strive for; his Mocs are modest, challenging instead skill and technique, and look like they'd be actual sets. His fun attitude, the aesthetic (fonts and border styling), and great music/ sound effects are also major pluses.
I am grateful that his early reviews of the summer wave made his channel as popular as it is today and I foresee great things in the future for him.
BTW what do you guys think is his best Moc?
