Riddle
Ok so this one here is like a riddle, or it reminds me of the riddler. I do like the overall space used and the fact you never left too much out in terms of the question marks. I do find just plain black for all the question marks to be a bit boring and I do not see why you didn't try to add color here and there to spice it all up. I do like this tho and I hope next time you'll do it in different colors.
~~THINGS TO IMPROVE ON~~
Try doing this with more different colors next time, as stated above.
