Your more detailed pieces such as the eye and the bike are very well done! Your drawings of people on the other hand could use some work. The kids in the earthbound drawing look really awkward, being in positions that don't make sense, positions that would be really uncomfortable. For example, Ness is holding up is right arm for no reason, and Paula isn't facing, or even looking at Porky. You should work on proportions and anatomy too, as Paula's arms are way too short, and Poo's legs are coming straight down, even though his feet land outside of his hips. I would look at references on the internet, and if push comes to shove, look at yourself doing things in the mirror.
Anyways, keep it up! I'm looking forward to seeing your progress over the year.
