Okok one last thing let me try to be more specific with the color pallete and color spectrum .There are on the colors one direct oposite of each one.For example the oposite of green its a red or a pink (depends on the tone) and you should always try not no mix this colors because they will usualy break the picture context and armony.
Here is a list of colors and oposites:

(note that the oposites are susually diferent natured.For example red is a heat color and green is a cold color)

Cold color---- Hot color
Green - Pink Red
Blue - Orange
Light blue- Red
Light blue green - Dark brown
Light green - purple

Since you have the combo of red and light blue and light green the picture looses a lot of it´s balance.Try not to mix cold colors with hot colors until you know how to break the color bounds.

It´s very good I like the coloring technique you used on this one.It looks smoth and well proporcionated.I like the bg even thou it´s hard to combine green with dark colors and dont overdue the picture with hard tones.For my personal like if you used many heat colors such as red and brown on the central picture try using light colors or cream colors on the bg so the picture armony will be kept.
