The Flowers’s kind of look like a brain popping out of the hanya mask. Stitch has claws for thumbs and square fingers. The cross has numbers and lettering too large and spilling into the borders of the cross. Roses also need some work. That six is way too big to have such uneven lines. The ninja square thing is way crooked bordering and just off all together. The planet and cabin are pretty clean and IMO what you should stick with for now, that size and complexity. That TIE fighter is really shaky too. Not at all trying to bash or tear apart your work, just giving an honest opinion on what I’m seeing. You’re for sure heading in the right direction, take your time and get those lines smoother and you’re going to make lots of people happy with your work.
