I like your drawings in the mind map and silly ideas. The ones in the mind map makes a great support with words and make the mind map fun to read. The ones in the silly ideas was clear and easy to understand, also looks funny which made the ideas looks “silly ” as well.
I wish you have spend more time in the play place. I admire your courage to go in there, and I believe that if you had stay for a bit more time you might “have some fun” for real XD. You might come up with some great ideas in those place with childhood memories.
What if you add the explanations for you ideas in the blog? One or two sentence will make the ideas really easy to understand, while reading the words in the picture sometimes could be a real pain.
