'This Way' looks interesting, but I think the random shading of the text could use more thought. The creature and candle look very nice, though, aside from the fact that the creature's nose is a mix of two shading styles.
My favorite part of 'Civil War' the hat, but the face is well-done as well. However, I tihnk the purple is a bit of a jump from the next skin tone, maybe look at making the ramp smoother. The lip color sticks out some and I think you could do without and save yourself a color. If you keep it, change the hue and/or saturation so it looks less out of place.
The Jazzalisk is interesting, but here, too, your ramp has a bit of an incongruity. Try a lighter color where you have the red shadow tone and see how that looks.
Given the shading style, I think the middle '? ? ?' looks the best. It looks embossed onto the BG and that fits how it's shaded.
Good luck and keep pixelling!
