Suffering for My Art

In the past year since I got my computer, I have done multiple assignments for my year of online graduate school, include two major papers.  I have downloaded over a dozen PDFs of books I had been wanting, including two where the download came free with the actual physical book.  I have played multiple games, including over two thousand rounds of solitaire.  I have been posting pictures and movies I have made with my computer.  I have joined some online groups, and even posted in a few of them when I felt that I had a pertinent point to make.  I have even posted in a forum.  However the one major thing I have left to do is make actual "art."  Sure, I have written the basic framework for an entire book, but I started that before I got this computer.  I've messed around with the basic graphic functions of Pages, Mac's word processing app, but I haven't actually made any artwork.  Back when I was in high school, many years ago, I was able to goof around with the school's Mac, which had a dedicated art program installed.  Wouldn't you know that Apple would drop such an app just before I would finally get mine.  This has bugged me from the start.  I have looked on the App Store for free art apps, but I am still unsure which one would be the best for me.  Some of the reviews I've seen have not been that kind.  Other apps are "free" for awhile, but I would either have to pay for premium services.  One even has a free trial, but it might stop working after the trial ends, and where would I be then.  My best chance is to wait until I update my Mac to the Catalina OP.  When that happens, I just might be able to gain access to new apps, ones that started on Apple's mobile devices. Sure, I don't have an iPhone or iPad yet, but I still might be able to get an app that still works.  Once I get a great art app, there is so much I could do.  I could finally get a logo for my blogs.  I have tried multiple times to get a perfectly square logo, but my screenshots wind up being a pixel off from true square.  I might be able to do better with the right app.  I have been thinking about creating my own supplements for the RPGs I like.  While there is already ready-to-use artwork for such endeavors, being able to add some extra touches would help me make such projects my own.  You know, give it some pizzazz.  Anyway, I just like creating things.  Look at some of my movies on YouTube or Facebook.  They are of me making logos for my store Booknotes. It is just dry erase markers on a white board, but the possibilities are greater than one would think of.  Just imagine what I could do digitally, if I just had the right setup.  So, I am still looking for recommendations for the best app for me.  I mean, just look at what I've done just with the Blogger capabilities. It is supposed to be a jack-o-lantern, but it might not transpose correctly when posted.  At least the puzzle in red will still work.  Can you figure out which one is missing? (I've previewed the page.  It doesn't look right.  Should and have cut and pasted it.)
