New character design

So Train face is on the bench and a new hero is needed, here's some sketches iv did to try to find the style to go for in the real world, im hesitant to chose a style at this point as i though of making it realistic to highlight the differences between styles but i dont want to do realism, so its probably going to be cartoony.

So far i like 3, 4, 7 and 8 for different reasons

I never know what eyes to give a character, so usualy en up just geiving them a solid color or black dots, but i liked the eyes in 7 and 9 too, 3 is just a little creepy.

Im going to get some sketches of the old man and the villan sorted out hopefully 2day.
