They're cute! C: I like the second one! You need to work on the body proportions on the first one and the lines on the second one need to be steady and not wiggly. Are you still doing the requests for the chibis?
I think your second style is a lot better than your first. The lines don't look very smooth though, so you should try to keep a steady hand and keep re-doing lines if they come out a bit wonky. Make sure you don't colour outside of the lines.
