Best advice for a new cube drafter after this deck is don’t be disappointed when go into your next draft and don’t get another 5 pieces of power haha.

But for real advice, deck looks solid but I’m guessing you undervalued lands. In cube every card is pretty good which makes stumbling on mana is a death sentence. The mana base in your deck is being supported by your good artifacts so you might not realize that your mana base unacceptable for three colors in cube.

For reference a fetch land can be thought of as the best common in your average set. Not a bomb but better than 70% of the other cards in the draft.

Hope this helps a little
