No this isn't my first time making a texture, I just forgot my old account info
well please C&C

I don't understand why did you put "rainbow" colors for the nose,but I like the "rainbow" thing at the hair.I don't think you should put those white colored tears at the eyes,it makes it look not weird.The smiles should be more longer like this .
All that I said above I just my opinion,btw i'd rate it 7/10 for overall.
