Looks alright. Hard to tell what the effects are with that much purple. The stuff I can see looks alright. Try to tone down the purple. Nice tag though.
Yeah, too much light color to tell what's what. It looks very flat. Basically it needs a higher tonal range.
The colors are wayy to bright. Next time use darker ones. You really need to work on your lighting and on your depth.
You need a darker purple for this gradient map to work. The contrast just needs to be greater so we can have a greater range of shade. ^_^
