The colors are too harsh and the effects blending scale is poor. You need to blend and smoothen your effects more. There are overcontrasted areas in the composition and places where the effects are too abrupt. This type of effect won't work all the time so keep other styles.
As for your 2nd one, I think the lighting is too strong and there isn't enough contrast. Also the composition of the effects are nice but they need better blending.
Keep at it!
lightings weird on the 2nd one
colors look awkward on the 1st one
The effects are oversharpened imo.
