Just doodles, although I did buy oil paint supplies and attempted to try oil painting once.
Oil painting is a hobby that to get set up you'll probably spend $300 for oil paints, canvas, supplies, easels, etc. and if you are sensitive to smells, the wet oil paints on canvas are drying for days and turpentine as well, really not great for highly sensitives.
Its still fun, but I recommend it only if you can store it all in an airtight container or have an art studio or a place to keep everything in another room as the smells can be obnoxious. I was happy that I tried it, but then it was an expensive thing to learn in a way too. Live and learn. I got as far as one painting of pears and still life though, just not very good.
I also have the water color and acrylics. I'd go with watercolor even though its supposed to be the hardest to get good at, just because its less messy and isn't obnoxious smelling.

The last one is a dream I had of an October moon while I was astral traveling to Italy or Greece.
I sometimes travel while I sleep, and this was a romantic dream I had.
