Overall not a bad drawing, a few things to consider other than what Huehen has said:
~Outlines around the bow, stern, forward 4"
and where the island meets the hull are a bit janky
~There's a weird grey line on the flight deck beginning after the 1st mast
~Incomplete portholes near the aft AA mounts
~Double black line running along the hull is a no-no
~The thingy behind the aft 4"
doesn't look like pixel art
~railings above bridge windows are unneccsary
~Life boats look like they came off of the old parts sheets, you can find better ones
here
~Those hurricanes you have didn't fly until 1935, and weren't introduced until 2 years later
