They look better in terms of more interesting but still have some problems
>>44354402Blue and green don't work together. No protagonist ever had those two colors for a reason. They drown each other out, not letting either to shine. That shade of green would look way more appealing with browns, grays, reds or even fucking oranges (see gardenia). That wouldn't be too much of a problem if there were more then two main colors but that brings me too.
>>44354427The red and blue works better but it's still very dull. It could use an extra color on the shirt or maybe a different colored backpack or maybe a deeper blue. The color combination just isn't very interesting and that brings down the design. Add more color or more interesting colors in tandem. It seems like your taking influence from RSE character designs by having them be simplistic but you aren't using colors as effective as they did.
