You have a good mix of derivations/figures and explanations (text), which makes easy to follow your thought process and is important to explaining the concepts. Your first two figures clearly show how to downsample a signal. Some small mistakes are a convolution symbol in your first derivation that should not be there, your sum for the expression of the DTFT of a downsampled signal should start from 0, and your last figure shows a different cutoff frequency than what you derived. Other than that, nicely done!
