Crooked image

I finally ordered a custom shirt to see if I liked it as much as the awesome stickers and coasters I ordered previously. I regret not sending a different file type because the text on my image is pixelated, that's my bad! But the really disappointing thing is that the whole image is really crooked on the shirt itself. I liked the feel of the material and everything else was great but I don't know if I'll try the T-shirts again.
