First of this is a lovely entree and the visuals are adorable. as an artist myself, a lot of it is very relatable, the inability of coming up with ideas is a constant fear to me, and always feeling like an "uncreative" creative type is not fun.
a lot of my ideas come randomly to me when I see something that acts as inspiration, but it's usually when I talk about it to my friends it goes from a passing thought to an actual idea I can use. most of my ideas are built from things I think are cool and things I want to make people feel (usually happiness.) but a lot of time when I try to sit down and create my mind goes blank and I feel stuck.
this proves you are very capable of creating wonderful things and I hope you do!
