2.5 out of 5 stars.

The 3 icons you’ve included are of an alright quality.
Although I do question wether the dino icon is blue or purple it’s looks more purple to me.
You could have included more than just 3 icons and added maybe at least 5 icons.
Similarly you could have include more sizes than just 16x16, 32x32 and 48x48.
If you improve the set drop me a personal message and I will review the set.
