Cowbunneh Shirt

I've recently drawn a Cowbunneh (Cowboy style Freezer Bunny) for fun, as some sort of challenge. Today I thought to myself, why not create a cute t-shirt for my Sims with this cute cowbunneh on it? I've spent hours on it. I did know how to create it, that wasn't the problem. The problem is that I cannot get the print in hi-res. As you can see, when zoomed in, the print is quite blocky. I tried my best to prevent this, but so far I haven't found a solution. If you know how to solve this, let me know! Once I find out how to increase the quality of the print on the shirt, I'll update the file here. Until then, I hope you guys don't mind it being a tad blocky. Furthermore I added a couple variations for the shirt colouring. As you can see on some of the screens, the ones with bright red/blue/green shirts, I played around with the seams. Every design has 3 channels. Freezer Bunny print is not recolorable.
