I like the small 3D style details that you've created (not sure if intentional or it just appeared that way due to effects stacking).
The lightning spots are overdone, the quality of them seem ruined/pixelated.
I like the idea behind Rick trying to grab the triangle but you could have blended it a bit better than that.
The theme/background could have been a space one with nebula style with a lowered opacity just to give that relaxed space-drinking theme.
The text is well done, though the green outline is overdone a bit.

Overall 5.8/10

Keep it up, would love to see more of your works!
