I agree with the change from the towel to the white cape. I know the towel is the "accurate" way to go but it hangs way too far down. This could cause him to trip over and we don't want that.
I'm with Fett4Real in that the jetpack can go a little higher. It still looks like it's drooping too far down.
Overall though, it is a vast improvement from the first pic! I think you did a stellar job fixing the helmet flare and the attention to the details in the suit are spot on! Nice Job
