Here is a quick texture pack I made using Gimp 2. Not all blocks are changed but a good few of them are. Once I figure out how to add my own pictures I will add them but for now you can test it out anyways.
This will probably get a lot of negativity (as it already is) and might possibly be locked.
You said you spent only an hour on it, it's not worth releasing since it's just a bunch of scribbles and basically the default texture.
I understand you were trying to go for a random theme, but there's a lot more potential to the word "random" than just scribbles and recolors.
TL;DR: put work in your texture pack before you release it. Even if it's going for a "random" theme.
Just to let you all know all this was intended. I am going to put effort into it and over the next week or two work on a nice texture pack changing even the armor. My friend was at my house so I just wanted post up my very first texture pack. That is all.
