I like how you showed the process of of your mind map, you went above the requirements to show your design process and I think that’s really cool! And good practice! Overall, your blog is really neat and pleasing to look at, great job on your mind map, you were able to make it expanded and complex while keeping it legible.
I wish that some of your sketches were expanded a little bit more. I think although you had titles and a brief description it would really help to demonstrate the purpose of the product and its functions.
What if you for the lakes and the shoes app for example, showed a what the lake checklist would look like? Maybe a map or a list form? Or on the self-tightening shoes, a close up of how the self tightening function works.
