RH21ND - 27

Too much colors and too this paint coat. Try to use 1 primary color and 1-2 additional. And thin down paint with water a bit.

Is the Schrodinger's Cat alive or not? Some strong colours, and signs of brush control for an early painter. Thinner coats will add a lot to the quality of future entries. Keep at it!

Yeah, hard to tell what's happening here.  Need to finish the base, too.  Plain black is alright if you must, but the smudged ring indicates it wasn't a priority at all.

Seems you use orange over green. Not good choice, painting separately is better

Multiple thin coats to achieve an even coverage will be a big step up. 

the color palette remind me of  he-man's tiger
 

The gloss of the paint spoils the work. A little matte polish can help. I would also suggest diluting the paint more and paying more attention to neatness

Looks very :3. As others already mentioned, the shine doesn't work in its favor. Matt coat, touch-up on the base and it's gonna look great.
