No crap, wise guy
Alright fine, I'll form my previous post in perhaps a more critique manner.
As I was saying, these decals are nothing but a short and simple use of color editing functions in the software you used. The simple yet horrific additions that you made have quite a few flaws: they aren't symmetrical when clearly intended to be, the lines are all misshaped which shows no use of the pen tool whatsoever, just a quick and awful job using the brush, and on top of that the choice of color is terrible.
In conclusion, these decals do not and never will appeal to the general users of Blockland. They are easy to make and on top of that, they are poorly made.
