It's a good set, maybe with more details become very good. 6/10

can I know why it is good or not good,im interested ,maybe an approximate price also

The desings look ok. The colours are ugly. Why there's pink? It's also very plain. Solid coloured areas and thick black lines. Everything looks flat.

Pate5 is right, some shading could make this set good.
I don't mind the pink though.
Try to make the details "pop" out more.

6/10 the head texture is nice but you need to improve the legs and arms a bit

Can you tell me a very small example on how to do this.Also by shading,do you mean putting shadows?The problem is I'm fairly good in designing but weak in effects.
