No problem! It's important to appreciate skills in others you wish you had. If you've never read Scott McCloud's "Understanding Comics" I think you would love it. He talks about the "Infinite Canvas" which is (to me) a loose metaphor for screens. If I taught UX/UI and Logo Design at an Art School, it would be one of the first books to throw at my students.
Every single one you've posted has been educational for me. Really helped to internalize good design more than reading theory.
I enjoyed that you also did the Mario mobile game. I don't think too many game designers would make half of the mistakes Nintendo did there, but it's amazing to see so many examples of poor design in one place.
Wow! Never come across useronboard, but now I've seen it I can't believe I went so long without it. For someone lacking experience in UI/UX this is fantastic.
Is it your website as well? If so, the mobile experience needs a few tweaks. Especially when viewed in portrait orientation.
The arrows to go back and forth are tiny, and very close to the slide window. Which, when your finger overlaps onto, jumps around and zooms. I thought maybe swiping would work, but it does not.
The top menu links are pretty tiny as well.
I thought it worth mentioning because the amount of work to fix it seems pretty low.
