Well...art is a great hobby.
The best thing about art is that it can look however the hell you want it to. You can use any materials and mediums you want to.
There is no "right" or "wrong" way to create a piece of art!
Get the "should's" outta your head..."It SHOULD look like this or that..." and you'll have a BLAST.
Art can.be drawn, painted, photographed, etc etc....it can be a combination of methods. It can be sculpted, created out of "trash" or scraps of things. Any. Thing. You. Want!
Creativity in general is a fantastic pastime. Playing guitar, writing poems/articles/stories/research papers, finding a sturdy old piece of furniture at a thrift or yard sale and loving it back to life with sandpaper/primer/paint etc...anything that gets your creative juices flowing.
Art is incredible...it occupies time and prevents boredom. It gives you an outlet for your emotions - can't express how you feel in words? Create some art that expresses how you feel, whether literally or symbolically. Once completed, you feel a sense of pride, accomplishment...you feel GOOD.
What's your creative history? Ever get into it?
Never ever EVER too late to start, and skill level doesn't matter.
Good luck in your search
Peace.
