30 - A Congrats Banner for Finishing the Challenge

I got to the end of this and learned quite a few things, as intended. Just need to clear up some stuff since I was asked. I worked for each challenge no more than one day, between my other daily work activities and even if I was unhappy with the results or thought they weren't polished enough I didn't revisit it (since it was about ability as much as it was about time management).  I used no photo textures, just brushes and usually regular round and chalk brush. For the photo studies I did no tracing of course and no color picking. For the real life studies I used no photos, just what I saw on my desk. How to learn otherwise?
