I'm pretty sure it's common for programmers to be below average visualizers. I was interested in this topic in college and asked around in my software developer friend group and many also didn't visualize well. My unscientific hypothesis is that programming requires a much larger language based memory than visual memory, so people sort themselves based on their skills.
However, this doesn't disqualify you from the arts under any circumstances! You might never be a photorealistic painter, but you might be better at, say, photography, as it's more about elimination of elements, or certain types of illustration (or music but I assume by "artistic" you meant visual arts). And, as usual, it's mostly hard work and only like 10% talent...
