Nice

This sounds a great deal like the song from the animation Ghost Crush by Andrew Kauervane.
It sounds like a cover, but a good one.

Hate: Blue outline on the digimon, super distracting and burns my eyes
Love: Color palette, the background has some really nice soothing tones

I think I get the concepts, but it's hard to tell because it's so blurred, honestly just don't use the default photoshop effects when you're drawing/painting in photoshop, they almost always look cheap/distracting.
Just keep practising and stop using photoshop filters/effects and you should do good.
(Guy on the left has cool mecha boxing gloves? and dude on the right has badass laser whip?)
Ps: not trying to be a douche, I honestly just want to help :s

Like the idea or concept of the image alot, it is a bit muddy/dark though, still very cool.
