@Manupix  Thanks a lot! Really! Thank you! I tweaked the palette and also downloaded Coffee, Slym, Cure and Indigo's works to study. Trying to understand them and implement what you said. Makes good amount of difference!

Have a look at the checker. You'll notice saturations are all mid-range (30-70 for extremes); most values are also medium.

You need more diversity so you have colors in your palette that help you solve problems, independently of where they 'should' be used. In particular you need near-neutrals to help bridge the color ramps, both in palette-space and locally.

Also badly needed is brighter highlights. Maybe just brighten the lightest teal?

Avoid pure black, doesn't work well with this palette.

Nice pixeling though =)

@ Knightsabers Thanks a lot for your advice! I completely see your point and it make sense. I really have to experiment and play with colours a lot more. I think this is also happening due to drastic difference in display of my HP Notebook's screen and that of my Iphone. 

I'm no master (check my profile to confirm that), but I'd say that the contrast in your colors changes up a lot. You have the blue to black for the arms, but then the green pants have very little contrast. If you made it more consistent, it might be a bit more... connected? I guess? 

Better example; the armguards. You have a yellow highlight, a yellowish orange mid tone, and then red. Right to red. The contrast changes up right in the middle of the ramp. Keep it consistent, and you might be happier. Good work though, regardless of the colors, the art itself is great ^-^

EDIT: The shoulderpads are not what I'm talking about; the darker red makes the shaping look good. But for a rounded object like the armguards, it looks weird having that much contrast.
