Thanks for the feedback.
For the numbers, I wanted them to be handwritten with multiple iterations, so that all the '1's don't look the same like in a handwriting font. I had two options, to draw the sprites myself or look for a pre-existing set. I ended up using a dataset that I had for machine-learning to identifying handwriting. They were very low resolution but I thought 'I can just sharpen them and they would look fine'.
So yeah, I should have drawn the sprites myself instead of trying to shortcut it. The current numbers looks terrible.
