Warriors C&C

Hi guys, I'm currently painting the salvagers box and I am 2/10. In relation to my painting skills I've done a pretty good job, but I am not really satisfied with the result and I don't know why. I'm feeling a little demoralized and I'm not motivated to go on with the box and was thinking about stopping to collect LoV. Could you help me figuring out what is wrong and/or how to improve the result? Thanks in advance
