Haha, it's surprising to see something like this come back after 2 years, but well done!
yeah, most of the colors in this are quite redundant. you can revise it by going back and merging the over-similar colors with each other.
Way too many colors. Almost looks like non-pixel art.
I just got a full time job just after starting out!
Luckily enough, I've got to practise some pixel art skills (faking it until I eventually got better at it)
