It looks nice. But it's pixel art of a Breloom, not a Breloom sprite. It helps to actually use the existing sprite as a reference point while you work, since that is the look your trying to simulate
#1: Your color palette is wrong. If your going to make a new sprite for an existing pokemon, make sure you use the same color palette of the old sprite, otherwise your just doing pixel art (or a new shiny coloration).
#2: Your sprite is too large. Breloom is 59 pixels tall. Your pixel-art is 79 pixels tall. When you make a new sprite of an existing pokemon, the size doesn't have to be exactly the same as the old sprite, but it should be similar. 20 pixels is too much to go unnoticed.
#3: There's too much light colored outline in certain places. Always use Black to color the bottom and bottom-right of any object, no matter what. Use less of your lightest outline color and replace it with your middle outline color. Don't use the light outline color unless that surface is facing directly at the sun (The outline on Breloom's face shouldn't be colored that way).
#4: Highlights are to big. This is majorly noticable on the neck petals, where you tried to use highlighting to accomplish what you should have done with shading. Highlights should be no more than 2 pixels thick vertically or horizontally unless the object is on dominates the sprite, or the object is flat is someway. Remember a highlight is the tiny sliver of an objects curvature that is facing directly at the sun.
#5: The neck petals are the wrong shape. Breloom has round petals on it's neck, not spikey ones.
